Coating Advantages PLATIT develops and produces coating equipment for plasma-generating PVD (Physical Vapor Deposition). Our products are based on: • Conventional cathodic ARC technology PL , • The unique LARC® technology (LAteral Rotating Cathodes) , ® ® • The unique LARC and CERC (CEntral Rotating Cathodes) technologies • High performance sputtering technologies • SCIL®: Sputtering induced by LGD® (LAteral Glow Discharge) • PL711 HIPIMS: High Performance Impuls Magnetron Sputtering • LACS®: Hybrid technology (LAteral Arcing with Central Sputtering) We hold a significant number of patents related to coatings, coating technologies, and processes. PLATIT coatings offer the highest standard of modern coating technology for tool steels (cold / hot work steel, high speed steel; HSS, HSCO, M42, ...) and tungsten carbides (WC). All work pieces can be coated with a programmable coating thickness between 1 and 18 µm. All batches are coated with high uniformity, ensuring the repeatability of the coating quality.
Cutting The PLATIT hard coatings reduce the abrasive, adhesive and crater wear on the tools for conventional wet, dry and high speed machining. All carbide tipped tooling must be manufactured with brazing material that contains no cadmium and no zinc. Cadmium and zinc are not stable under the high vacuum at the coating process temperatures. Braze outgassing will ruin the strength of the joint, contaminate the tooling surface and the vacuum chamber.
Punching, Fine Blanking PLATIT technology ensures an increase in tool life through special structures and by reducing friction on punches and on fine blanking tools.
Forming For forming applications such as extrusion, molding, deep-drawing, coining, PLATIT hard coatings reduce friction, wear, built-up edges and striation. Repolishing of functional surfaces is recommended. The PLATIT hard coatings increase productivity for plastic forming and forming machine components with better release and lower wear. Low roughness and excellent surface texture improve part release and influence injection forces in the mold to allow shorter cycle times. For parts with a mirror finish, repolishing after coating is recommended. Due to physical limitations, deep holes and slots are seldom coatable.
Tribology
14
PLATIT hard coatings solve tribological problems with machine components that can be coated at temperatures of 200-600°C. Due to the hardness (up to 45 GPa), abrasive wear is reduced. This leads to higher reliability for dry operations, and environmentally damaging lubricants can be replaced.
