Study of Composite Spark-Alloyed Coatings Based on Titanium Carbide Using Self-Propagating High-Temperature Synthesis

摘要

This work discusses composite coatings obtained by electro-spark alloying and self-propagating high-temperature synthesis. It has been established that the generated composite coatings consist of titanium carbides, which are uniformly distributed in the metal matrix. The titanium carbide grain sizes are in the range of 0.1-4.0 ìm. The coarse grains of titanium carbide in the coating consist of disperse carbides with sizes of less than 1 ìm. The study of the structure of the composite coatings in friction tracks has demonstrated that the generated coatings possess high wear resistance.
