9860788 This Small Business Innovation Research (SBIR) Phase I project will develop glow discharge plasma coatings and arc discharge plasma coatings using implantation to relieve stress and enhance adhesion. These will be designed to replace wet chrome plating technology and conventional titanium nitride. These coatings will scale at low cost to high energies, with the attribute that they will conform to the treated surface like a wet coating. These processes are expected to be environmentally benign and to provide flexible control over the morphology and chemistry of the coating. Phase I will combine the use of low energy plasma ions which provide conformal vapor deposition-like coatings with medium energy ions which provide ion beam mixing and non-equilibrium solid solutions. These processes will produce a modified surface zone, well integrated with the substrate material, which can be deposited over a wide range of thickness from submicron to several tens of microns. The plasma source consists of an arc discharge in conjunction with a gas feed to fabricate the chromium nitride (CrN) hard coatings used in the tool industry. This technology may eliminate the present need to use environmentally damaging wet processes, such as hard chrome plating, and yet reduce the net cost. It is anticipated to provide a cost-effective surface hardening method which will increase coating thickness and provide for improved coating adhesion.

9860788 这个小型企业创新研究 (SBIR) 第一阶段项目将开发辉光放电等离子涂层和电弧放电等离子涂层，利用注入来缓解应力并增强附着力。 这些技术旨在取代湿法镀铬技术和传统的氮化钛。 这些涂层将以低成本扩展到高能量，其特点是它们将像湿涂层一样贴合处理过的表面。 这些工艺预计对环境无害，并能灵活控制涂层的形态和化学性质。第一阶段将结合使用提供保形气相沉积涂层的低能等离子体离子和提供离子束混合和非平衡固溶体的中能离子。 这些工艺将产生一个改性表面区域，与基材材料很好地结合在一起，可以沉积在从亚微米到几十微米的各种厚度上。 等离子源由电弧放电和气体供给组成，用于制造工具行业中使用的氮化铬 (CrN) 硬质涂层。 该技术可以消除目前使用对环境有害的湿法工艺（例如镀硬铬）的需要，同时降低净成本。 期望提供一种成本有效的表面硬化方法，其将增加涂层厚度并提供改进的涂层粘附力。
