Description

technical field

[0001] The invention relates to the field of metal materials, in particular to a TiC / 316L composite material and a preparation method thereof. Background technique

[0002] As a modern structural material, 316L stainless steel plays an important role in industrial development and technological progress. 316L stainless steel is an austenitic stainless steel with superior mechanical properties. Because of its nonmagnetic and excellent welding performance, it is widely used in many fields such as machinery, chemical industry, marine, light industry and petroleum. With the continuous development of modern industry, the requirements for the performance of 316L stainless steel materials are also constantly increasing. Equipment using 316L stainless steel in high temperature, high pressure and other environments are often scrapped due to inner wall wear and oxidation corrosion, and the life of the machine is severely shortened. 316L stainless steel belongs to aust...
