Abstract
The method of ultrasonic vibration assisted coating preparation has been widely concerned. In this study, (CoCrNi)88Al6Ti6-cBN composite coatings were prepared on GH4169 via ultrasonic vibration assisted high-speed laser cladding. The influence of ultrasonic vibration power on the forming quality, microstructure, hardness, and wear resistance of the coatings was studied. Based on the effect of fine grain strengthening and dispersion strengthening, compared with the coating without ultrasonic vibration, the grain size is reduced by 43 %, the hardness is increased by 16 %, and the wear resistance is increased by 30 % when the ultrasonic vibration power is 1200 W. This study can provide ideas for the research of nickel-based alloy coatings.
期刊介绍：
This journal is a platform for publishing innovative research and overviews for advancing our understanding of the structure, property, and functionality of complex metallic alloys, including intermetallics, metallic glasses, and high entropy alloys.
The journal reports the science and engineering of metallic materials in the following aspects:
Theories and experiments which address the relationship between property and structure in all length scales.
Physical modeling and numerical simulations which provide a comprehensive understanding of experimental observations.
Stimulated methodologies to characterize the structure and chemistry of materials that correlate the properties.
Technological applications resulting from the understanding of property-structure relationship in materials.
Novel and cutting-edge results warranting rapid communication.
The journal also publishes special issues on selected topics and overviews by invitation only.
