Tribo-Mechanical Properties of HVOF Deposited Fe(3)Al Coatings Reinforced with TiB(2) Particles for Wear-Resistant Applications

This study reveals the effect of TiB(2) particles on the mechanical and tribological properties of Fe(3)Al-TiB(2) composite coatings against an alumina counterpart. The feedstock was produced by milling Fe(3)Al and TiB(2) powders in a high energy ball mill. The high-velocity oxy-fuel (HVOF) technique was used to deposit the feedstock powder on a steel substrate. The effect of TiB(2) addition on mechanical properties and dry sliding wear rates of the coatings at sliding speeds ranging from 0.04 to 0.8 m·s(−1) and loads of 3, 5 and 7 N was studied. Coatings made from unreinforced Fe(3)Al exhibited a relatively high wear rate. The Vickers hardness, elastic modulus and wear resistance of the coatings increased with increasing TiB(2) content in the Fe(3)Al matrix. The wear mechanisms strongly depended on the sliding speed and the presence of TiB(2) particles but were less dependent on the applied load.
