Numerical simulation of metals spray deposition process

According to the characteristics of spray deposition process of metals, the complicated relations among the process parameters have been discussed. The complicated relations are very difficult to be discussed by a simple physical equation. Internationally, the method of computer modeling is widely used. The common computer modeling procedure has been introduced in this paper. Mainly, the modeling method of the three processes of spray deposition has been researched. The modeling results and the experimental data have been compared, which shows the validity of the modeling results. Finally, the main difficult problem of the spray deposition has been discussed.
