摘要: The laser alloying of the Ti-5.5Al-2Zr-1Mo-1V near alpha-titanium alloy surface by boron carbide particles was performed. pulse radiation is melting specimen a alloy, while simultaneously feeding BC powder to zone. powerful impulse effect obtained microexplosion above sample. explosive acoustic wave sample accelerates carbide. titanium where charged particles. partial and dilution with molten bath on alloy. new phases TiC, TiB, TiB2 dendrites-shaped fine-dispersed needles were formed. microhardness coefficient friction alloyed increased into 2 1.5 times respectively.
