摘要

Splat generation of metal particles on substrates is a very important process for a variety of depositions techniques like plasma thermal spray. In this article an analytical and a numerical model are presented to describe the heating and melting process(heating with phase change), using adequate boundary conditions, global thermal capacity and the Stefan condition at the interface. An analytical dimensionless expression is determined for the temperature distribution as well the position and velocity of the moving liquid-solid interface in terms of Bessel functions. Comparison with the numerical results are carried out.
