abstract = "Another key parameter that affects the coating depositionefficiency of cold gas dynamic spray technology is the contactangle. The particle tangential sliding on the substrate at impactis due to the gas flow bow shock at a supersonic velocity whichis liable for the erosion at the surface of the substrate. This studypresented a finite element approach of a numerical model toinvestigate the profile of the deformed sprayed particles underthe condition of oblique impact and the erosion mechanism forsolid particle impact on ductile material during Cold GasDynamic spray. In the numerical modelling of cold gas dynamicspray (CGDS) by a Lagrangian approach that was developed,oblique erodent particle on the substrate at controlled contactangle (100-900), velocity (500 m/s) and friction coefficient (0.3)was simulated. It was discovered that in the substrate, the craterdepth decreases as well as the area of contact between thesubstrate and the deformed particles when the contact angleincreases at the same impacting conditions. The materialremoval and crack formation mechanism were also simulatedsuccessfully by the accumulation of residual strain that resultedin the dynamic detachment of material elements at the surface asthey fail.",
