A hybrid implicit—explicit finite element methodology for coating formation in the high-velocity oxy-fuel spraying process

Abstract

A finite element (FE) based methodology is presented for simulating the high-velocity oxy-fuel (HVOF) coating process. The methodology involves a hybrid of explicit and implicit FE analyses to simulate both particle impact and layer deposition and thus furnish both temperature and residual stress distributions resulting from the process. The methodology is illustrated for an HVOF sprayed copper coating on a copper substrate and for a SS 316 HVOF sprayed coating on a SS 316 substrate.
