Abstract
A Large Area Filtered Arc Deposition System (LAFAD) including a rectangular two-channel macroparticle filter and two rectangular cathodic arc sources allows the production of vacuum coating deposition on articles of complex shape, with practically unlimited height. In this process a pure, strongly ionized gas-metal plasma flow containing multicharged ions without macroparticle impurities is created. The interaction of this plasma flow with the negatively charged substrate results in the deposition of coatings with an amorphous and ultra-microcrystalline structure. These coatings are characterized by a number of unique mechanical properties such as: high microhardness, high corrosion resistance and low friction. This allows the coatings to be used for improving wear resistance of marine diesel parts: Application of LAFAD equipment allows several surface modifications and coating steps to be performed in one uninterrupted process.
