摘要：
The present investigation deals with the fabrication of a novel thermally sprayed coating using a diamond reinforced molybdenum feedstock. Molybdenum powders were ball-milled with 10 wt% mono crystalline diamond particles to produce a powder feedstock. Both milled and as-received powders were deposited on steel substrates using air plasma spraying to produce coatings with a thickness in the range of 250-280 um. Characterisation of the coatings was performed in terms of micro-structure, phases, hardness, elastic modulus and residual stress. Retention of diamond in the composite coating was confirmed using Raman imaging. Micro-hardness and elastic modulus of coatings improved with diamond reinforcements. (C) 2018 Elsevier B.V.
