Investigation into Corrosive Wear of the CoCrFeNiTax Laser-Clad Coatings on TC4 in the Neutral and Alkaline Circumstance

CoCrFeNiTax (x = 0, 1) coatings were prepared on the surface of TC4 by laser-cladding to improve corrosive wear property and extend its service life in media, ultimately aiming performance. The effects Ta addition phase constituent microstructure first investigated. Given wide application media (even undergoing friction), covered with was especially focused two (neutral alkaline). results showed that composed primary α(Ti) eutecticum (α(Ti) + Ti2Ni) as matrix TiC reinforcement. introduction increased volume fraction made more uniform. coating performed outstanding resistance than other samples media. rate 4.7458 × 10−4 mm3·N−1·m−1 neutral environment 6.6808 alkaline environment, 64.45% 61.79% lower those TC4, respectively. mechanism is a combination serious micro-cutting, active dissolution, oxidation, effectively improved micro-cutting.
