Environmentally Benign Processing of Stainless and Nitrided Stainless Steel Coatings Using Jet Vapor Deposition

涂层广泛用于保护金属表面免受腐蚀和环境退化。严重的环境危害与最广泛的涂层工艺，如电沉积和油漆，刺激了环境友好的涂层技术的发展。Jet Process公司开发了一种环保、高速率、低成本的涂层工艺——Jet Vapor Deposition （JVD）。除了作为一种实用、环保的替代方案，JVD还具有沉积多组分涂层的能力，并且具有出色的成分控制。不锈钢是一类多组分材料，其耐腐蚀性能是众所周知的。Clayton教授等人，本提案的合作者，以及其他人最近的工作表明，氮合金化导致不锈钢耐腐蚀性的显着改善：特别是对于含Ni和Mo的不锈钢。使用JVD合成不锈钢和氮化不锈钢涂层的初步工作非常有前途：它表明JVD提供了在室温左右合成此类材料涂层的实际可能性。因此，在拟议的第一阶段计划中，他们将专注于JVD不锈钢和氮化不锈钢的合成，并展示它们的耐腐蚀性。该计划的第二阶段扩展将包括应用于各种表面和扩大涂层工艺。这些目标的实现将导致一种经济、无污染的工艺合成不锈钢和氮化不锈钢涂层。

Coatings are widely used to protect metal surfaces from corrosion and environmental degradation. Serious environmental hazards associated with the most widespread coating processes, such as electrodeposition and painting, have spurred the development of environmentally benign coating technologies. Jet Process Corporation has developed an environmentally benign, high rate, low cost coating process, Jet Vapor Deposition (JVD). In addition to being a practical, environmentally sound alternative, JVD also has the capability to deposit multicomponent coatings with excellent compositional control. The corrosion resistant properties of stainless steels, a class of multicomponent materials, are well known. Recent work by Prof. Clayton et al, the collaborators in this proposal, and others has shown that nitrogen alloying leads to significant improvements in the corrosion resistance of stainless steels: especially for stainless steels containing Ni and Mo. Preliminary work on synthesizing coatings of stainless and nitrided stainless steel using JVD is extremely promising: it suggests that JVD offers the practical possibility of synthesizing coatings of such materials at around room temperature. Consequently, in the proposed Phase I program, they will focus on the synthesis of JVD stainless steels and nitrided stainless steels and demonstration of their corrosion resistance. Phase II extensions of the program will include applications to a variety of surfaces and scale-up of the coating process. Achievement of these goals will result in an economical, pollution-free process for the synthesis of stainless and nitrided stainless steel coatings.
