Based on the process of laser cladding Al/Ti composite powder above 7050 aluminum alloy, and by using an orthogonal experiment, an optimized cladding coating parameters are achieved with the laser power of 1.5 kW, the scanning speed of 150 mm/min and the defocusing amount of 50 mm. The highest temperature in the laser spot center is obtained from the simulation under the parameters in the orthogonal experiment. Using the range analysis, the relative significances of the three respective parameters, laser scanning speed V, laser power P and defocusing amount S are achieved in the order, from big to small. By analyzing sizes of the molten pool and several typical curves of sample temperature changing with the scanning direction in the condition of the orthogonal experiment, it has been discerned that the bonding strength of the sample front is poor because its molten pool depth in the substrate is too small to obtain a good combination between the cladding material and the substrate; moreover, the deformation and ablation occur at the sample end due to the substantial temperature accumulation origining from its poor heat dissipation. The grain morphology of Al/Ti cladding coating is mainly cellular dendrites with equal and dense distributions.
