Cold spray deposition of aluminum powders on polyethylene reinforced with glass fibers has been studied. Different processing conditions, including different stratifications of the fiber-reinforced polymer used as a substrate, have been investigated to better understand the deposition mechanism. The experimental campaign has been conceived and tailored to highlight the influence of several process parameters on the deposition of the first layer of particles. The results obtained allowed to highlight and clarify the influence of standoff distance and gas pressure and also gave some insights concerning the effect of the substrate stratification. Guidelines regarding the design of the manufacturing process have been also released.

研究了铝粉在玻璃纤维增​​强的聚乙烯上的冷喷涂沉积。为了更好地理解沉积机理，已经研究了不同的加工条件，包括用作基材的纤维增强聚合物的不同分层。已经构思并定制了实验活动，以突出几个过程参数对第一层颗粒沉积的影响。所获得的结果可以突出和阐明对峙距离和气压的影响，还可以对基材分层的效果提供一些见解。还发布了有关制造过程设计的准则。
