Ni-Cr-Si-B-Fe-C Thermal Sprayed Coatings Refused Under Vibratory Treatment
<p>The paper presents studies of vibratory treatment effect on the microstructure and hardness of thermally sprayed and re-fused Ni-based coatings. Ni-Cr-B-Si-Fe-C system powder has been deposited on the S235 steel substrate and re-melted with the simultaneous introduction of the horizontal me...
