Problems solved by technology

However, its toughness is very poor, its brittleness is large, and it is not wear-resistant, which restricts its excellent performance and practical application.
The development of metal coatings has solved the defects of ceramics and increased the range of use and comprehensive performance of ceramics. However, the existing metal coatings still cannot meet the needs of the market, and a better metal coating is urgently needed.

Description

technical field [0001] The invention belongs to the field of ceramics, and relates to a nickel-chromium alloy coating for ceramics and a preparation method thereof. Background technique [0002] As a common ceramic material, ceramics have the characteristics of high temperature resistance, wear resistance, corrosion resistance, high hardness, etc., and they have a wide range of sources and are cheap. However, its toughness is poor, its brittleness is large, and it is not wear-resistant, which restricts its excellent performance and practical application. The development of metal coatings has solved the defects of ceramics and increased the range of use and comprehensive performance of ceramics. However, the existing metal coatings still cannot meet the needs of the market, and a better metal coating is urgently needed. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide...
