Description of the invention (0 (please read the precautions on the back before writing this page) I The present invention is about a treatment method of high silicon and high hardness on stainless steel surface, especially about a high silicon and high silicon on stainless steel surface The processing method of hardness laser alloying. The stainless steel mesh is widely used because of its better corrosion resistance. However, generally the stainless steel pin has a lower hardness and poor wear resistance, so its application in wear resistance is more limited. If a wear-resistant coating layer with high hardness can be formed on the surface of the stainless steel mesh, the application of stainless steel in wear-resistant can be greatly expanded. The thickness of the hardened layer of infiltration radon in these methods is not deep, and the hardness decreases by 10 with the depth from the surface position, so the wear life is not long. Therefore, the development trend of stainless steel surface jet hardening is that the thickness of the hardened layer is deep and the hardness is uniform. Treatment method: The wear-resistant hardened surface modification methods currently used in the commercial preparation of stainless steel surfaces with a deep hardened layer thickness and uniform hardness are ion mization method and plasma nitridation method. Because these methods need to be operated in a vacuum environment, and have the disadvantages of 15 time-consuming and energy-consuming; therefore, the current development direction is a simple, time-saving, energy-saving and pollution-free wear-resistant hardened surface modification method. On the other hand, if the content of silicon in stainless steel increases, it can not only improve its resistance to high-temperature gasification, but also improve its resistance to local corrosion (such as: pitting corrosion Or gap corrosion, etc.). From resource saving and cost-effective 20% stickiness, a high-silicon alloy layer is formed on the surface of the stainless pin by surface modification, in addition to retaining the original moderate strength and weight of the stainless steel mesh. In addition, on the other hand, it can also strengthen the corrosion resistance and wear resistance of the non-sickle net. In order to develop a simple, time-saving, energy-saving and pollution-free wear-resistant hardened surface modification method, in the present invention, by covering High silicon alloy layer on the surface of non-sickle dysprosium-5)-This paper scale is applicable to the Chinese National Standard (CNS> A4 specifications (210 X 297 mm) 82.3. 40,000 214569 _§- «Energy Consumption Cooperation of the Central Bureau of Standards of the Ministry of Economy Du Printed A6 B6 V. Description of the invention (2) To improve the silicon content and hardness of the surface of the non-sickle mesh, and to increase the corrosion resistance and wear resistance of the stainless mesh. The purpose of the present invention is to provide a method of using two-gasification laser The method of modifying the surface of the coated silicon oxide to condense the non-sickle surface. The method used in the present invention is to first mechanically (mainly grinding or grinding sand, etc.) remove the surface of the non-sickle and connect it to the eaves machine. After cleaning, the surface of the stainless steel pin is coated with polyethylene yeast as the solvent @ 化 晶 凝 睡 (0. 01 ~ 1 · β thick), after drying treatment (40 ~ 100¾), it can be cooled by Xunchen Precise mold numerical control X-γ workbench, under m gas atmosphere, with two gasification sulphur laser under different power (100 ~ 400W, power density range (50 ~ 500 kW / c · 2 >, and Under the relative moving speed of different workpieces / laser beams (0 ~ 1 bright w / sec), the melting treatment of "point", " line " or " plane "is applied, and the workpiece after» among treatment Ultrasonic Yingtong was washed in clean water to complete the alloying treatment of the surface shot. The main purpose of the above-mentioned grinding or sandblasting of the surface of the stainless steel net is to remove impurities or vaporization on the surface of the workpiece, so as to avoid the embedding of impurities into the alloy layer during the laser surface coating process and affecting the properties of the alloy layer. At the same time, the roughness of the surface of the stainless steel will increase after this treatment, so it can promote the adhesion of the silicon carbide. When grinding, you can use 1 volume of ~ 硪 化 silica sand paper, and when using sand, you can use silica sand or other natural ores as granules. In addition, the raw material used in the alloying treatment of the laser surface coating is radon silicon condensed with polyethylene yeast as a solvent. After the temperature decomposition, the silicon can be dissolved into the surface layer of the non-scythe to lift off the surface of the non-scythe net. Silicon contains manganese and hardness. The main role of polyethylene yeast is to carry radon silicon. This paper uses the Chinese National Standard (CNS) A4 specifications (210 X 297 mm) 82.3 · 40,000 -----------:!.!
