利用高功率半导体激光器在不锈钢(AISI 304)上进行了侧面激光熔覆制备铝基涂层的实验研究。这些涂层在燃料电池或催化转化器等领域具有重要的应用价值。采用完全析因法确定了主要工艺参数(即激光扫描速度、辐照度和送粉率)与熔覆层的主要几何特征(高度、宽度和深度)之间的关系。此外，还考察了涂层的微观结构以及工艺参数对工艺成本的影响。这些关系导致了加工图的确定，以便用作选择适当的铝和合金激光熔覆工艺参数的指南。(C)2014爱思唯尔B.V.保留所有权利。
The production of aluminium-based coatings on a stainless steel (AISI 304) substrate by side laser cladding, and using a high-power diode laser was experimentally studied. These coatings are very interesting for potential application such as fuel cells or catalytic converters.Correlations between the main processing parameters (i.e. laser beam scanning speed, irradiance, and powder feeding rate) and the main geometrical characteristics of the clad track (height, width, and depth) were determined using a full factorial method. Furthermore, the microstructure of the coatings and the influence of the processing parameters on the costs associated to the process were examined. These relationships lead to the determination of processing maps in order to be used as a guideline for the selection of proper processing parameters for laser cladding of aluminium and alloys.
