摘要： A plasma-based method for the deposition of diamond-like carbon (DLC) coatings is described. The process uses a radio-frequency inductively coupled discharge to generate a plasma at relatively low gas pressures. The deposition process is environmentally friendly and scaleable to large areas, and components that have geometrically complicated surfaces can be processed. The method has been used to deposit adherent 100-400 nm thick DLC coatings on metals, glass, and polymers. These coatings are between three and four times harder than steel and are therefore scratch resistant, and transparent to visible light. Boron and silicon doping of the DLC coatings have produced coatings having improved optical properties and lower coating stress levels, but with slightly lower hardness.

摘要： A process for forming an adherent diamond-like carbon coating on a workpiece of suitable material such as an aluminum alloy is disclosed. The workpiece is successively immersed in different plasma atmospheres and subjected to short duration, high voltage, negative electrical potential pulses or constant negative electrical potentials or the like so as to clean the surface of oxygen atoms, implant carbon atoms into the surface of the alloy to form carbide compounds while codepositing a carbonaceous layer on the surface, bombard and remove the carbonaceous layer, and to thereafter deposit a generally amorphous hydrogen-containing carbon layer on the surface of the article.

摘要： Process for forming adherent coatings using plasma processing. Plasma Immersion Ion Processing (PIIP) is a process where energetic (hundreds of eV to many tens of keV) metallic and metalloid ions derived from high-vapor-pressure organometallic compounds in a plasma environment are employed to deposit coatings on suitable substrates, which coatings are subsequently relieved of stress using inert ion bombardment, also in a plasma environment, producing thereby strongly adherent coatings having chosen composition, thickness and density. Four processes are utilized: sputter-cleaning, ion implantation, material deposition, and coating stress relief. Targets are placed directly in a plasma and pulse biased to generate a non-line-of-sight deposition without the need for complex fixturing. If the bias is a relatively high negative potential (20 kV-100 kV) ion implantation will result. At lower voltages (50 V-10 kV), deposition occurs, and the extent of the surface modification can routinely be extended between 1 &mgr;m and 10 &mgr;m. By combining plasma based implantation and film deposition, coatings with greatly reduced stress are possible, allowing the ultimate coating thickness to be expanded to tens of microns.
摘要翻译：使用等离子体处理形成粘附涂层的方法。等离子体浸入离子处理（PIIP）是一种在等离子体环境中由高蒸气压的有机金属化合物衍生的能量（几百eV至几十keV）的金属和准金属离子用于将涂层沉积在合适的基材上的工艺，随后在等离子体环境中使用惰性离子轰击释放应力，由此产生具有所选组成，厚度和密度的强粘附性涂层。利用四个工艺：溅射清洗，离子注入，材料沉积和涂层应力消除。目标直接放置在等离子体中，脉冲偏置以产生非视距沉积，而不需要复杂的夹持。如果偏置是相对较高的负电位（20 kV-100 kV），则会产生离子注入。在较低的电压（50V-10kV）下，发生沉积，并且表面改性的程度可以常规地在1m和10um之间延伸。通过组合基于等离子体的植入和膜沉积，可以大大降低应力的涂层，使最终的涂层厚度扩展到几十微米。
