Description

  The present invention relates to a method of manufacturing a coating layer of a component, and relates to a method of manufacturing a coating layer of a component that covers the surface of a high-performance component.

  Currently, the parts used are roughly classified into two types: contact type and non-contact type. The non-contact type consists of one using magnetism or one using air pressure. However, the non-contact type has a high manufacturing cost, a high cost for system adjustment and equipment repair, and a complicated structure. For this reason, contact-type rotating and sliding parts are used for parts, except when used in equipment with high accuracy and high value.

  The sliding part uses a method of adding lubricating oil between two sliding elements, and the member having lubricity includes a lubricating pad or a soft material. The method of adding the lubricating oil is economical. However, the above-described method is not practical because it cannot be sealed because lubricating oil is added, and contamination by oil must be avoided. In addition, the soft material easily wears and can be exchanged, so that it can be used as a substitute for the sliding body against the wear and loss of the main body. However, there is a problem that soft materials wear out. Therefore, the size and accuracy of the positioning are greatly changed, and the soft material is worn, and a large amount of fine particles are generated to seriously contaminate the system. Lubricants include lubrication pads or bearings, and are used in large quantities in related industries because they have the functions of linear motion and rotational motion elements that the lubricating oil automatically seeps out, with a low average price. Has been. Since the size can be easily set in the combination of the rotating shaft and the bearing, the sound generated during rotation is relatively small. Therefore, the small fan has a wide range of applications. However, since the consumption of the lubricating oil and the oil penetration rate are affected by the temperature at the time of operation, the density of the material, and the high coefficient of friction of the surface, a moving body with a high motion speed has a short service life. For example, the lubrication type bearing has an average service life of about 20,000 hours, which is far from the 50,000 hours of ball bearings, which limits the application.

  The rotary moving body is composed of a conventional rotary bearing, has a relatively long service life, and can be subjected to a slight inclination or a relatively heavy axial load when the shafts are combined. Therefore, the rotating element includes a support member in the axial direction or a part of the shaft. In a linear motion body, a plurality of rotary shaft devices are always fixed on a straight rail to perform linear motion. However, due to the problem of noise caused by contact and collision between the rotating shaft and the rail, the average price is high, and the use of lubricants including bearings is highly demanded for the adjustment technology of the linearity combination of multiple ball bearings. Limited.

  THE GLACIER METAL CO. , LTD, and registered in the UK, Japan, USA, Canada, France, Italy, Germany, Switzerland, etc. (Japanese patent registration numbers 223605, 438282). Not provided. Bronze powder is burned and connected on a steel alloy to form multiple holes, filled with a mixture of Teflon and lead, a thin film of Teflon lead is formed on the surface, and a Teflon lead is usually provided on the bearing surface for friction. By reducing it, it is not necessary to use lubricating oil. The Teflon lead has a bronze sintered layer with a thickness of about 0.3 mm, and a portion damaged by friction due to rotation is about 0.01 mm. The steel alloy secures the bearings and reinforces the strength needed for size precision, stability and precise tightness. Products manufactured by the above-described manufacturing process are applied to sleeves, bearings, flange sleeves, slide boards, and the like. FIG. 1 discloses a cross-sectional view of a product. The aforementioned technique forms a layer with multiple holes in which the bronze powder is sintered on the surface of the processed steel alloy material, and fills the surface with a mixture of Teflon and lead to form a thin film of Teflon lead. Form. Bronze powder sinters the surface with multiple holes as a filler for Teflon leads. The material and the bronze powder bond at high temperatures, but if they do not reach high temperatures, they are easily peeled off and separated. Further, since the bronze powder does not sinter unless it reaches about 760 degrees, the steel gold material is deformed by heat, and after filling the surface with a plurality of holes with a mixture of Teflon leads, the heating temperature is 360 degrees. At this point, the Teflon lead and the bronze filling material are bonded to each other. The high temperature manufacturing method generates harmful gas from Teflon, and the sintered layer is 0.3 mm thick and 0.01 mm is lost due to friction in the initial stage, so it is practical for moving bodies that require micro precision. And lead contained in raw materials violates environmental protection regulations for information-related products (ROHS was established in 2006 by the EU (European Union) in order to protect and conserve the global environment) (Restriction of the use of the certain Hazardous Substantial in electrical and electrical equipment) command), which greatly affects the utility value.

In order to describe the manufacturing method and characteristics of the coating layer of the component in detail, a specific example will be given and described below with reference to the drawings.

  FIG. 2 discloses the manufacturing process of the present invention. According to the drawing, the bronze-based alloy powder obtained by spraying is screened 10 and then mixed with a small amount of alloy metal material at a certain ratio to powder of different diameter (0.5-30 μm), and lubricated as necessary A mixing operation 30 is performed in which the agent 20 (for example, graphite, fatty acid amide, etc.) is added and mixed.

  The mixing operation 30 is performed to increase the uniformity of the chemical and physical properties of the raw material, and uniformly mixes particles of various different diameters using the principle of particle movement. The mixing speed and the mixer structure affect the uniformity of the mixing process for mixing the powder, so when performing the mixing process, match the characteristics of the powder, such as differences in particle size distribution and specific gravity. Therefore, a mixing process is performed in which segregation does not occur. In the present invention, an upright spiral leaf-type mixer is used according to the characteristics, and the mixture is uniformly mixed at a rotational speed (60 to 120 rpm).

  The sufficiently mixed powder is filled in the hollow mold of the pressure, and the upper and lower punches and the hollow mold are pressed to press-mold the powder 40. The pressure to be molded and the contact area of the punch and the expected density of germ cells are very much related. It is most preferable that the density of the final embryo cell is maintained at 7.9 to 8.0 g / cm 3 or more obtained by analyzing the result of the experiment 50 of the embryo cell. If the density of the germ cells does not reach the above-mentioned standard, the finished product can meet the demand, but it increases the subsequent manufacturing process and affects the quality stability. Therefore, since molding is performed at the most preferable density, it is necessary to stabilize the quality of the product when mass production or manufacturing costs are reduced.

  The lubricant used in the molding process is used to assist the release of the germ cells, and reduces the pressure due to the release. There are two methods for smooth release. One is mixing dry lubricant with metal powder, filling the mold directly, and pressing. The other method is a method of lubricating the inner wall of the mold. That is, before filling the metal powder into the mold, a liquid lubricant dissolved in a highly volatile organic solvent is applied to the inner wall of the mold and the surface of the punch or sprayed, and the organic solvent is volatilized and dried. After that, a lubricating layer is formed on the inner wall of the mold to achieve the effect of smooth release. In the experiment of the present invention, pressure molding is performed using a copper alloy powder to be electrolyzed or a powder having an appropriate particle size. When the lubricant is not added, the density after molding the embryo cells reaches 7.97 g / cm 3, and the most preferable density in molding the embryo cells can be obtained.

  The molded embryo cells are sent to a sintering furnace and a sintering process 60 is performed in a reducing gas. Sintering uses thermodynamics and diffusion studies to raise the temperature and effectively adjust the air in the furnace to generate a diffusion phenomenon that makes the powder partially solid or liquid and binds the powder . In the manufacturing process of sintering, variables including time, temperature change, air in the furnace, gas flow rate, time for holding at high temperature, furnace structure, etc. are important. Thus, any of the above-described elements is indispensable in order to achieve preferred sintering.

Sintering is performed in the following three steps.
1. Preheating area: The effect of degreasing and dewaxing is achieved by thermal energy, and the powder is not deformed in the dewaxing process.
2. Sintering area: After dewaxing treatment in the preheating area, the embryo cells are densified with higher-temperature heat energy.
3. Cooling area: After processing at high temperature, the metal structure and properties after forming are determined by adjusting the cooling rate when cooling.

  In any case, dewaxing and degreasing must be performed. Therefore, degreasing by appropriate preheating is a condition for obtaining preferable sintering. The temperature in the preheating area must be determined by the type of lubricant. For example, the commonly used zinc stearate can be dissolved at 130 degrees, vaporized at 260 degrees, and completely removed at about 427 degrees. The temperature of the preheating area of the present invention is set based on 450 degrees in consideration of the characteristics of the lubricant. In addition, if the heating rate is too high or the temperature is too high during the sintering process, the lubricant in the preheating area accumulates carbon on the surface of the product due to decomposition of the components of the compound, and the product is easily deformed. Burst. Therefore, it is very important to adjust the sintering speed. As a result of experiments conducted several times in the present invention, preferable sintering results can be obtained by adjusting the product sintering speed to 45 to 44 mm / min.

  The sintering area is provided based on the nature of the material to be sintered. Materials with different components utilize different sintering temperatures, sintering air and gas flow rates. In the present invention, a belt conveyor type continuous sintering furnace is used in the sintering process. As a result of repeated experiments, the temperature from the preheating area to the sintering area is set to 710 to 730 degrees, the temperature of the sintering area is set to 800 degrees plus or minus 5 degrees, and the sintering time is 25 to 35 minutes. Is set. In adjusting the air in the sintering furnace, since the present invention utilizes decomposed ammonia gas according to demand, it can be heated to decompose the ammonia to obtain air in the furnace. For this reason, the sintered area has a strong reducibility, but carbon is not deposited and is suitable for copper sintering.

  The cooling area includes a cooling area and a quenching area. The cooling area is sent from the high temperature sintering area to the quenching area to prevent the furnace from being deformed by a rapid temperature change. The quenching area is set to a temperature at which the sintered product can be transported or processed in a predetermined time. In the experiment of the present invention, the temperature of the product sintered at the aforementioned sintering speed can be lowered if it remains in the cooling area for about 30 minutes.

  All of the sintered products are somewhat deformed. If the required accuracy of the product is not very high, the product can be directly subjected to surface quality correction and coating treatment. On the other hand, in the case of a product that requires high accuracy, the size adjustment 70 is performed, and then a covering process is performed.

  After the size adjustment 70, the sintered product is degreased 90 by heating on the surface. Depending on the type of oil or fat, the quality of the surface coating layer is affected unless the oil or fat on the surface is removed by washing with an aqueous or acidic solvent or by performing ultrasonic degreasing 80. FIG. 3 discloses a structure diagram of the surface of the sintered product.

  After performing processing such as sintering and size adjustment, the product is coated on the surface using the density of powder and particles as a filler in a subsequent process.

A fluid produced from micro- and nano-level microparticles based on a small amount of polytetrafluoroethylene is added to electroless nickel plating, and the microparticles are uniformly dispersed in the synthetic electrolyte. The fine particles have an average diameter of 90 to 500 nm and occupy 3 to 10% of the total mass of the composite plating solution. After stirring uniformly with the power stirrer 100, the stirring speed is set based on the uniform suspension of all particles in the synthetic electrolyte, and the synthetic electrolyte in which metallic nickel ions and nano-micro particles are uniformly mixed is set. Form.

  In a situation where it is not necessary to apply voltage, the metal ions in the solution are present together with the reducing agent in the synthetic electrolyte on the solid surface through catalysis, and the metal ions are reduced to a solid metal by a chemical reaction. Very fine particles of 30% polytetrafluoroethylene are mixed and deposited on the surface of the solid. In the aforementioned reaction, when the reaction starts, electrons conduct directly when the substance in the solution reacts on the surface of the solid, not through the external conductor. For this reason, the temperature of the manufacturing process must be maintained at 90 degrees.

  In the manufacturing process of the present invention, a synthetic electrolyte layer having hardness, wear resistance, and a low coefficient of friction is formed. The electrolyte layer has an average friction coefficient that is ½ that of the nickel-phosphorus electrolyte layer. However, before coating treatment, cleaning of the surface of the material, for example, surface activation treatment 200, 400, surface quality improvement treatment 300, 500, water washing 110, 210, 310, 410, 510, etc. If it is not performed reliably, the quality of the coating layer will be greatly affected.

The main components of the chemical electrolyte are:
1. Metal ions: become metal in the electrolyte layer.
2. Reducing agent: reducing metal ions to metal.
3. Catalyst: the surface of the material has a catalytic appearance.
4). Complexing agent: prevents precipitation of hydroxide, adjusts the analysis rate, prevents decomposition of the electrolyte bath, and stabilizes the electrolyte bath.
5. Stabilizer: Absorbs extras other than fine particles, prevents spontaneous decomposition of the electrolyte bath, and extends the life of the electrolyte bath.
6). Buffer: Adjust the pH value within the working range.
7). Wetting agent: smoothes the surface.
8). Dispersion: Covers an ultrafine abrasive material.

  As the reducing agent, sodium hypophosphite is usually used. The pH (PH) value adjusts the P content of the electrolyte layer. When the pH is relatively high and the P content is low, the properties of the coating layer change. A coating layer having a low P content has lower corrosion resistance than a coating layer having a high P content, and a coating layer having a P content of 8% or more is not magnetic. In the surface coating layer of the present invention, when the P content is 6% and the volume ratio of polytetrafluoroethylene reaches 30%, the surface coating layer becomes nearly black. When the P content is 9% and the volume ratio of polytetrafluoroethylene is 20%, the surface of the coating layer becomes glossy gray, and the effect of the entire coating layer is very close to the experimental result. The electrolyte layer on the surface is black, and the hardness of the electrolyte layer that has not been heat-treated reaches 280 to 380 VHN. After the treatment, baking is performed at a high temperature of 300 to 350 ° C. for 10 to 15 minutes. An adhesion treatment 800 is performed on the surface of the substrate. The adhesion treatment post-baking has a clear influence on the crystal structure of the coating layer.

The product subjected to the adhesion treatment 800 is subjected to ultrasonic cleaning 900 for about 2 to 5 minutes according to the demand for accuracy of the manufacturing process, washed again, and subjected to the electrochemical reaction 600 of the material not completely coated yet. A change in size occurs when the particles on the surface are peeled off. Since the thickness of the coating layer is adjusted in the range of 6 to 12 μm, the product 1000 can be adjusted with a very high size accuracy. FIG. 4 discloses the state of the surface after the surface of the coating layer is adhered.
〔Experimental result〕

  In the experiment of the method of manufacturing the coating layer of the parts manufactured according to the present invention, the low coefficient of friction, wear resistance, high hardness, small size change, precise, low manufacturing cost, just increase the action of motive energy. As a result, the amount of wear on the coating layer surface was only about 0.1 to 0.2 μm.

The manufactured products have the following physical and chemical properties:
1. The range of temperature change is about 30-200 degrees.
2. Protect with inertia layer to prevent chemical and vapor corrosion action.
3. The low coefficient of friction showed little wear in a 30 day cooling fan test, and even after adding a very small amount of lubricating oil, the wear after 250 days was less than 1 μm.
4). Tensile strength, which is the tensile strength of the surface of the machine, reaches 200 kgf / cm2.
5. The thermal conductivity coefficient is about 0.5, and the thermal expansion coefficient is adjusted to about 5 to 10 / degree depending on the components.
6). The thickness of the layer after improving the surface quality is uniformly thin and difficult to peel off, so that the precision of the product can be maintained even after long-term use.
7). There are no fine pores on the surface to make the cells dense.

〔結果と討論〕 At the same time, as disclosed in FIGS. 5 and 6, the present invention applies the technology to a rotary bearing of a DC fan. As a result of experiments conducted, MTBF (Mean Time Between Failures) exceeded 5000 hours. The results of the test are shown in the attached Tables 1 to 5. The service life of the present invention can be applied to a wide range of bearings, and can also be applied to parts that perform linear motion.

For this reason, it can be applied to a sliding body of linear motion and rotational motion, and the manufacturing system is enhanced, resulting in a product that is better than conventional products.

  At the same time, when the material of the metal powder for powder metallurgy placed in advance is processed by the method of shaving the metal, in the present invention, the average surface roughness value (Ra value is about 0.6 to 0) in the surface of the material. .8) is adjusted accordingly. As for the surface of the material, the change in the profile of the cross-sectional height appropriately becomes a filler in the subsequent process, and has the physical and chemical properties of the product obtained in the aforementioned manufacturing process.
