Abstract

The invention relates to a process of preparing plasma composite depositing wear-resisting nickle- base surface alloy layer, belonging to field of surface composite wear- resisting gradient material preparation. It comprises preparation of nanometer oxidant particle composite coating layer, special granular variety selection and process of producing biglow multicomponent depositing nickle- base alloy on said coating layer. The invention is characterized in that the added nanometer oxidant is nonconductor, so it will not influence the corrosion resistant property of nickle- base alloy, and the rigidity of alloy layer is dramatically increased which is favourable for increasing corrosion resistant performance.

Description

technical field [0001] The invention provides a method for plasma composite plating infiltration and corrosion-resistant nickel-based surface alloy layer, which is suitable for the preparation field of advanced surface composite corrosion-resistant gradient materials, and involves the addition of particle material types and surface preparation processes of various advanced materials. system integration. Background technique [0002] Corrosive wear is a material loss phenomenon that occurs when a material is subjected to friction and undergoes chemical or electrochemical reactions with the environmental medium, referred to as abrasion. Corrosion-resistant and wear-resistant alloys must be able to withstand the synergistic damage of mechanical and electrochemical factors from the material design. The design ideas for the composition and structure of corrosion-resistant and wear-resistant alloys are different. Corrosion-resistant alloys usually add alloy elements to enhance t...
