Abstract

The invention discloses a plasma nonmetal ceramic alloy technology which is used for performing surface modification on small, light and thin parts. The plasma nonmetal ceramic alloy technology is characterized by comprising the following steps: controlling the temperature of processing parts in a vacuum container to be lower than 200 DEG C, and using nitrogen gas, silane and borane to perform ionpermeation on processing surfaces of the parts. The plasma nonmetal ceramic alloy technology reduces a production environment temperature, can perform surface modification on small, light and thin parts, does not cause outlines of the parts to deform, improves surface hardness of the small, light and thin parts, improves wear resistance, reduces abrasion between friction pairs, and prolongs the service lives of the parts.

Description

technical field [0001] The invention relates to the technical field of heat treatment and infiltration on the surface of small, light and thin parts, in particular to a plasma non-metallic ceramic alloy technology. Background technique [0002] The traditional surface heat treatment infiltration process for small, light and thin parts has the following defects: (1) High nitriding temperature is easy to cause shape deformation for small, light and thin parts; [0003] (2) The ammonia gas used in the nitriding process pollutes the environment and causes great harm to operators. Contents of the invention [0004] The plasma non-metallic ceramic alloy technology proposed by the invention completely solves the problems that the shape deformation of small, light and thin parts caused by excessive production temperature, the production and use of working gas ammonia pollute the environment, and cause great harm to operators. [0005] The purpose of the present invention is achie...
