Problems solved by technology
However, due to the presence of oxide films and loose layers of 1-5 μm on the surface of stainless steel parts after nitriding treatment in the prior art, this not only reduces the surface roughness of the parts and the surface quality of the parts, but also reduces the surface quality of the parts. affect the use of parts
Therefore, the existing nitriding treatment method for stainless steel parts is still not ideal.

Abstract
The invention discloses a surface finishing method of a stainless steel component after nitriding, and an apparatus thereof. An abrasive particle injection method is employed in carrying out finishing processing on the surface of the stainless steel component after nitrogen treatment; that is, abrasive particles are injected on the surface of the stainless steel component after nitrogen treatment through an abrasive injector head, with the injection pressure value of the injected abrasive particles of the abrasive injector head as 0.1-0.5MPa. The method and the apparatus of the invention are advantaged in removing the surface oxide film and the loosening layer of the stainless steel component after nitriding, improving the surface quality of the stainless steel component after nitriding, and not damaging the component. The apparatus of the invention further have the advantages of convenient operation and simple structure. The method and the apparatus of the invention not only can be applied in the surface processing of the stainless steel component after nitriding, but also can be applied in the surface polishing processing of other precision components, thereby further improving the surface roughness of the precision components.
Description
technical field [0001] The invention relates to a surface finishing method and device for stainless steel parts after nitriding, and belongs to the technical field of parts surface treatment. Background technique [0002] At present, in the prior art, parts made of stainless steel after nitriding treatment are often used to replace parts made of high-tech steel materials. This kind of stainless steel parts after nitriding treatment not only has the advantages of low cost, but also has corrosion resistance, High life and other advantages. However, due to the presence of oxide films and loose layers of 1-5 μm on the surface of stainless steel parts after nitriding treatment in the prior art, this not only reduces the surface roughness of the parts and the surface quality of the parts, but also reduces the surface quality of the parts. affect the use of parts. Therefore the mode of the existing nitriding treatment of stainless steel parts is still not ideal enough. Contents...
