Development of metal matrix composite powders for low pressure cold spraying

太平洋微粒材料有限公司（PPM）面临的直接行业问题是缺乏金属基复合材料（MMC）粉末，这种粉末可以通过任何低成本、低压、便携式冷喷涂系统沉积。该项目将是开发碳化钛(TiC)-镍（Ni） MMC粉末的可行性研究，该粉末可以通过低压冷喷涂沉积，而无需将TiC和Ni作为单独的粉末成分进行机械混合。这项研究的结果将成为进一步研究开发低成本、低压、便携式冷喷涂系统粉末的起点，以制造耐磨损和耐腐蚀涂层。

The immediate industry problem at Pacific Particulate Materials (PPM) Ltd. that the proposed project to be supported by this Engage Grant aims to resolve is the lack of a metal matrix composite (MMC) powder that can be deposited by any low-cost, low-pressure, portable cold spray system. The proposed project will be a feasibility study on the development of titanium carbide (TiC)-nickel (Ni) MMC powders that can be deposited by low-pressure cold spraying, without the need to admix mechanically the TiC and Ni as individual powder components. The results of this research study will serve as an initiation point for further studies in the development of powders for low cost, low pressure, portable cold spray systems to fabricate wear and corrosion resistant coatings.
