Low-temperature DLC film deposition device (multi-layer ta-C, hydrogen-free)
It is now possible to achieve low-temperature DLC (Diamond-like carbon) thin film hard coatings with improved adhesion compared to conventional ta-C!
High-density and stable high-quality film formation is possible! By performing DLC film formation that is highly hard (wear-resistant), has a low friction coefficient (wear-resistant), is corrosion-resistant, adhesion-resistant, and smooth, we contribute to the longevity of mold parts for semiconductor manufacturing equipment, resin molding molds, sliding components, and tools. This is not only optimal for reducing customer costs but also for reducing maintenance work hours, such as cleaning tasks, and for business improvement. It is also possible to achieve "high adhesion, smooth & hard low-temperature DLC film formation" for three-dimensional ultra-precise complex-shaped molds and machine parts. In addition to improving hardness and wear resistance, we also accept "peeling treatment and re-coating," contributing to the reduction of product life cycle costs and material waste, thus reducing environmental impact. ++++++++++++++++++++++++++++++ DLC stands for Diamond-Like Carbon, which refers to a hard thin-film coating with good sliding properties that has intermediate characteristics between diamond and graphite. By adjusting the ratio of SP3 (diamond bonds) to SP2 (graphite bonds) and the ratio of H (hydrogen) contained within, as well as by applying multilayer coatings, it is possible to create thin films with various physical properties and characteristics (industrial value).
