Abstract: Al2O3 particle-modified Fe66Cr10Nb5B19 metallic glass matrix coatings were deposited on carbon steel substrates by detonation spraying of the corresponding powder mixtures. The microstructure, mechanical and tribological properties of the coatings were investigated. In the microstructure of the coatings, the Al2O3 particles were located between the layers of the Fe66Cr10Nb5B19 amorphous alloy. The bonding strength between the substrate and composite coatings was ~ 130 MPa. The wear behavior of the coatings was studied under dry linearly reciprocating conditions in a ball-on-flat mode using a WC-6Co ball as a counterbody. It was found that the friction coefficients of the Al2O3-free coating and composite coatings were close to each other and varied in the range of 0.64–0.70. The specific wear rate of the coatings modified with 1.5 and 4 vol.% of Al2O3 was 2.5 × 10−5 and 3.1 × 10−5 mm3 N−1 m−1, respectively, which is about one-fifth of the specific wear rate of stainless steel. It was suggested that the dominating wear mechanisms of the Fe66Cr10Nb5B19-Al2O3 composite coatings are fatigue and abrasion wear.
