The present invention relates to a method for applying a surface hardening material in the form of solid particles to a part.

は、溶接ビードが均一な厚さをもたなくなるという欠点
を有している。Although various electroplating methods are known for applying coatings to surfaces, such techniques are limited to the formation of relatively thin layers. To address this issue, the spraying method is generally used when attempting to form a thick layer.However, since this method is ``visual'', the thickness of the formed coating may be significantly inconsistent. It has the major drawback of being uniform.
Another method is to bond by welding. However, this method also has the disadvantage that the weld bead will not have a uniform thickness if it cannot easily follow the surface topography of the article to be coated.

。(Structure of the Invention) A method of applying a surface hardening material having wear resistance and/or corrosion resistance to an article having an irregular surface according to the present invention includes dispersing it in a fiber matrix of polytetrafluoroethylene. a step of arranging a sheet made of a surface hardening material such that it is not in direct contact with the irregular surface of the article having an irregular surface to be coated with the surface hardening material, but is very close to the irregular surface; placing a surface in a pressure-responsive flexible housing with a hardfacing material and a brazing material suitable for contacting and covering at least a portion of the irregular surface; and applying pressure to the exterior of the housing. applying a force to the sheet of hardfacing material to bring it into direct contact with the irregular surface by deflecting the housing; and heating the surface hardening material to a temperature sufficient to form a coherent mass that adheres to the irregular surface of the article.
