对冷喷涂和激光粉末床熔融沉积工艺进行了探索，发现可显着增加模压硬化硼钢-铝接头的峰值力和断裂能。使用 250 µm 厚的 316L 金属中间层通过电阻点焊到 AlSi 涂层模压硬化钢和 6022-T4 铝合金上。此外，沉积的 316L 内的铝渗透促进了机械锁定效应，这是通过将激光粉末床熔化过程中的舱口间距从 100 µm 增加到 200 µm 来评估的。
Cold spray and laser powder bed fusion deposition processes were explored and found to significantly increase the peak force and fracture energy of the press hardened boron steel–aluminium joint. The use of 250 µm thick 316L metallic interlayers was resistance spot welded to an AlSi-coated press hardened steel and 6022-T4 aluminium alloy. Moreover, aluminium penetration within the deposited 316L promoted a mechanical locking effect which was assessed by increasing the hatch spacing in the laser powder bed fusion process from 100 to 200 µm.
