MoAlB ceramic coatings were prepared on a 316 steel surface by atmospheric plasma spraying with different arc power levels. The phase composition, microstructure and wear resistance of against GCr15 Si3N4 counterparts studied. decomposed was oxidized to form MoB Al2O3 during spraying. With the increase power, experienced more decomposition, but became denser. When increased from 30 36 kW, rates...
