| Abstract Scope |
Engineering components subjected to harsh tribological conditions, such as drilling in geothermal systems, experience accelerated wear and erosion. Surface engineering offers cost-effective solutions to extend component life and improve performance. This study evaluates three surface treatment approaches to mitigate abrasive and erosive wear in two low-alloy steel materials: (1) hardfacing via metal matrix composite cladding, (2) high-temperature electrochemical ultrafast boriding producing iron boride surface layers exceeding 200 µm, and (3) high-entropy material-based thermal spray coatings approximately 2 mm thick. Abrasive wear resistance was evaluated using the ASTM B611 standard test protocol, and erosion resistance was assessed under controlled laboratory conditions. All three surface treatments significantly improved both abrasive wear and erosion resistance through distinct mechanisms, which will be discussed in detail. These findings support the development of advanced surface engineering strategies for components operating in extreme environments, such as geothermal drilling and other demanding industrial applications. |
