Abstract
En 中文
Highly demanding service conditions are common for engineering components used in applications, such as aerospace, power generation, marine, chemical processing, and paper manufacturing. In such situations, degradation processes, such as wear, corrosion, and erosion, and their interactions, can dramatically affect the integrity of the structure and shorten its useful life. Thermal spray technologies have proven to be a valuable surface-engineering tool for solving these problems and improving the durability of critical components. High-velocity oxygen-fuel (HVOF) spraying has received much attention as one of the thermal spray processes capable of producing high-density, high-bond-strength, and low-porosity coatings at lower processing costs. HVOF can fire molten or semi-molten particles at high velocity onto the substrate to form dense microstructures and achieve good bond strength between the coating and the substrate. The properties of HVOF coatings make them highly desirable for a wide range of applications that demand high wear and corrosion resistance. This review will discuss the HVOF process, its working principle, and its advantages and disadvantages in detail. Moreover, the effects of the various coating materials and process parameters on the mechanical, tribological, and microstructural properties formed are critically discussed. This article seeks to establish the correlation between process parameters and coating properties, highlight key parameters that influence material behavior, and suggest future trends for optimizing HVOF surface engineering solutions.
