摘要: This paper concerns the modeling of cladding using an Nd:YAG laser operating at low powers typically less than 800 W. Experimental observation evolution mass clads shows two power thresholds. The theoretical study relies on a calculation fluence provided to substrate and model heat transfer into substrate. We suggest that first threshold is required for melting. second when powder directly melted by beam therefore liquid contacting
