Microstructure and Microhardness of Ni/Al-TiB<sub>2</sub> Composite Coatings Prepared by Cold Spraying Combined with Postannealing Treatment

Ni/Al-TiB<sub>2</sub> composite powders were deposited on the surface of 316L stainless-steel substrates by cold spraying at gas temperatures of 250 and 450 &#176;C, respectively. Then, the as-sprayed coatings were annealed at 650 &#176;C for 10, 20, and 30 h. The experimental re...
