IN SITU SYNTHESIS OF TiB2 WHISKERS IN THE LASER CLADDING Fe-B COATINGS
Fe-Ti-B激光熔敷层中TiB2晶须的原位合成

In order to reduce the high brittleness of laser clad Fe-B coatings, the Fe-Ti-B composite coating with TiB2 whiskers reinforcement was developed by laser cladding with a powder mixture of 640 and Fe-Ti alloy. Compared with Fe-B laser cladding coating, the cracking resistance of the Fe-Ti-B composite coating is obviously improved, while its hardness is not impaired.
