Abstract
AbstractThe present paper reviewed the role of factors influencing the wear properties of iron alloy‐based coating material. In brief, these factors are categorized into four major types such as substrate properties, high‐velocity oxy‐fuel spraying parameters, heat treatment processes and wear testing parameters. Substrate properties include roughness, thermal resistance, and adhesive strength between substrate and coating materials. High velocity oxy fuel parameters include spray distance, oxygen flow rate, fuel flow rate, angle of spray, spray density, coating speed, thickness, number of coating layers etc. Erosion wear testing parameters include impact speed, impingement angle, erodent discharge, slurry concentration etc. Furthermore, erosion wear testing parameters are sub‐categorized into three types which are particulate‐based parameters such as size, shape and hardness of particle, impact‐based parameters such as angle of impact, impact velocity, and composition‐based parameters such as microstructure, physical and mechanical properties of materials. The annealing process speeds up the development of crystal phases. Therefore, to get the best coating materials, a detailed investigation and optimization of all the factors must be performed.
