Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
The following embodiments of the present invention provide an alloy material for a bridge surface and a detailed description of the bridge.
The alloy material for the surface of the car bridge frame comprises the following raw materials in parts by weight: 65-85 parts of aluminum oxide, 20-25 parts of titanium nitride, 15-25 parts of zirconium dioxide, 20-35 parts of TPU, 3-10 parts of iron powder and 0.5-2.2 parts of rare earth element powder.
The alloy material of the invention takes aluminum oxide, titanium nitride and zirconium dioxide as main acting substances of the alloy material. Which respectively have the following characteristics of aluminum sesquioxide chemical formula Al2O3It is a high-hardness compound with a melting point of 2054 ℃ and a boiling point of 2980 ℃. The titanium nitride crystal has stable structure, high melting point, high hardness and good chemical stability. Zirconium dioxide has high temperature resistance,Stable chemical property, oxidation resistance, non-volatility and the like. The three components are mutually matched, so that the alloy material has higher hardness and stable chemical and physical properties under the matching required by the application.
The TPU is named as thermoplastic polyurethane elastomer rubber, and the TPU product has the characteristics of good cold resistance, good impact resistance, good wear resistance and high mechanical strength. The alloy material is used as the alloy material for the surface of the axle frame, is heated and melted in the 3D printing process and then is coated on the surface of the axle frame, so that the alloy material can be firmly adhered to the surface of the axle frame, and the wear resistance of the coating can be improved. For the car bridge with the surface often generating friction with the wheels, the service life of the car bridge can be greatly prolonged. The TPU with the proportion can ensure that the TPU is uniformly mixed with all components after being melted and has good adhesion performance, and simultaneously, the hardness value of a coating formed after the alloy material is coated is not reduced. Preferably, the particle size of the TPU powder is 50-500 microns. When the TPU powder is in the particle size range, the TPU powder can be fully mixed with other powder.
Iron is a silver-white metal that is flexible and ductile. The iron powder can be alloyed with other components in the alloy material to play a role in strengthening the hardness of a coating formed by coating the alloy material. The iron powder with the proportion can ensure that the alloying effect of the iron and other components is the best.
Rare earths are 17 elements of lanthanide elements in the periodic table of chemical elements, lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu), and elements closely related to 15 elements of the lanthanide series, yttrium (Y) and scandium (Sc), and are called rare earth elements. The rare earth elements are ferromagnetic and mostly have high hardness. The coating has an attraction effect on iron powder when added into an alloy material, when the rare earth element and the iron are uniformly distributed in the alloy material, the interaction of the rare earth element and the iron can enable the coated coating to be more compact, and the coating also has a certain magnetic adsorption effect on the frame bridge body because the frame bridge body is made of alloy. Because the alloy material needs to be coated after melting, in order to prevent the agglomeration of the iron and the rare earth elements, the melted alloy material is uniformly stirred, and the agglomeration phenomenon of the iron and the rare earth elements can not occur under the condition of high viscosity of the melted TPU. Preferably, the rare earth element is a yttrium group rare earth element (also called heavy rare earth element) with better magnetism. The yttrium group elements are elements having atomic numbers of 39 and 64 to 71, i.e., gadolinium (Gd), technetium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu), and yttrium (Y).
Further, the raw materials for preparing the alloy material also comprise 1-1.8 parts of ferroferric oxide. The ferroferric oxide has stronger magnetism and can generate mutual attraction with all ferromagnetic substances. The attractive force between the ferromagnetic powder is increased due to the addition of the powder, so that the coated coating is more compact, and the capability of adhering the alloy material to the vehicle bridge is stronger. Preferably, the particle size of the ferric oxide powder is 50-250 microns.
Further, the raw materials for preparing the alloy material also comprise 10-25 parts of chromium powder. The chromium is the metal with the highest hardness, and the chromium in the proportion can act together with aluminum oxide, titanium nitride and zirconium dioxide to improve the hardness of the coating. The particle size of the chromium powder is 50-250 microns
Preferably, the particle size of the ferric oxide powder is 50-250 microns. The particle size of the chromium powder is 50-250 microns. The particle sizes of the aluminum oxide, the titanium nitride, the zirconium dioxide and the iron powder are all 50-250 micrometers. The particle diameter is difficult too big, and the particle diameter too big can make each powder mix not enough, and the particle diameter also should not the undersize, and the particle diameter undersize not only can make the material cost increase, still can make the coating surface too smooth, can cause frictional force not enough, and there is the potential safety hazard in the motion of vehicle on the frame bridge that the coating has alloy material. Therefore, when the particle size of each metal powder or metal oxide powder is 50-250 microns, the performance of the finally prepared alloy material layer is better.
Further, the raw materials for preparing the alloy material comprise the following components in parts by weight: 70-80 parts of aluminum oxide, 20-22 parts of titanium nitride, 20-22 parts of zirconium dioxide, 24-28 parts of TPU, 7-10 parts of iron powder and 1-1.5 parts of rare earth element powder, the coating formed by coating the prepared alloy material has the best hardness, the best wear resistance and the best chemical and physical stability.
According to the alloy material for the surface of the car bridge, the aluminum oxide, the titanium nitride and the zirconium dioxide are used as main acting substances of the alloy material to interact under the condition of a proper proportion, so that the hardness of the alloy material is higher, and the adopted TPU can increase the wear resistance and the mechanical strength of a coating after the alloy material is coated and can enable the alloy material to be firmly adhered to the surface of the car bridge; the rare earth element powder has magnetism, and the rare earth element powder and the iron powder attract each other, so that an alloy material layer formed by coating is more compact, and the effect of adhering to a vehicle bridge is better. The components are matched with each other in a better proportion, so that the alloy material layer formed by coating the alloy material for the surface of the bridge frame has the characteristics of high hardness, good wear resistance and stable physical and chemical properties.
