title = "Determination of the thermal contact coefficient for a molten metal droplet impinging on a substrate",
abstract = "The behavior of a molten metal droplet impinging, spreading and solidifying on a solid substrate is relevant to many processes such as splat cooling and spray deposition. In this work, we have conducted experiments aiming at the study of the cooling and solidification of a molten metal droplet after impact. Measurements of splat temperature were conducted after the drop impact. Some results are presented to illustrate the effect of superheat and substrate material on cooling rate. We have also calculated an estimate of the value of the thermal contact coefficient by matching the experimental data to predictions of a heat transfer and phase change model. The results suggest that the value of this coefficient may decrease during solidification by up to an order of magnitude; for the case of a splat on metal substrates. For splats on quartz or glass where there is good bonding, however, the process can be adequately modelled with a constant value of the heat transfer coefficient.",
