Low-temperature DLC film deposition device (multilayer CrN/TiAIN, hydrogen-containing Ti-based)
Multi-layer film formation enables the creation of low-temperature DLC (Diamond-like carbon) thin film hard coatings with improved impact resistance!
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 parts, and tools. This is not only optimal for customer cost reduction but also for reducing maintenance work hours such as cleaning tasks and improving operations. It is also possible to achieve "strong adhesion, smooth & hard low-temperature DLC film formation" for three-dimensional ultra-precise complex-shaped molds and machine parts. In addition to improving high hardness and wear resistance, we also accept "peeling treatment and re-coating," contributing to the reduction of product lifecycle 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 possesses 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).
