The FeAl intermetallic compound coatings were deposited by low pressure plasma spray, air plasma spray and high velocity oxy-fuel spray. The influence of three kinds of thermal spraying processes on the microstructure, microhardness, elastic modulus and fracture toughness of coatings was investigated. The results show that the FeAl coating deposited by low pressure plasma spray presents special mechanical properties such as higher microhardness and elastic modulus as well as lower fracture toughness, when compared with those by atmospheric plasma spray or high velocity oxy-fuel spray.
