Mathematical Modeling of High Velocity Oxygen Fuel Thermal Spraying: An Overview

Abstract High velocity oxygen fuel (HVOF) thermal spraying is a versatile technique widely used for the manufacture of coatings from various materials system. The physical, mechanical, and chemical characteristics of a coating are critically influenced by the operating parameters used to obtain maximum coating performance while minimizing experimentation. In this paper, modeling of HVOF thermal spray processes is reviewed, paying particular attention to combustion, gas/particle dynamics, particle impingement, and coating formation.
