Abstract

The wettability of titanium, zirconium, chromium diboride and titanium carbide with melted Ni-based self-fluxing alloy of Ni—Cr—Si—B system has been investigated. The contact angle of the TiC wetting with melted alloy is equal to 49º. The contact angle in the ZrB2—(Ni—Cr—Si—B) system is equal to 40º. The Ni-based alloy wets TiB2 with the formation of contact angle of 34º. The alloy is spread along the CrB2 surface with formation of contact angle equal to 17º. The TiB2—(Ni—Cr—Si—B) system was chosen for the new gas-thermal coatings production because of good wetting and minimal interaction between the components of melted drop and hard boride.
