Study on Preparation and Properties of TiCrAlN Film on the Surface of H13 Die Steel by Multi-arc Ion Plating

This paper studies the influence of substrate bias on structure and performance multi-arc ion plating TiCrAlN film surface H13 die steel. Using technology, by controlling adjusting size bias, different structures properties are prepared steel substrate. The research results show that when voltage gradually increases, number large particles decreases, particle distribution becomes more uniform, density increases. When rises to 100V, is least, evenly distributed, quality best. micro-hardness film-base bonding force increase with continuous voltage. At film's reach maximum value, but exceeds a certain range, microhardness base greatly reduced; voltage, corrosion resistance increase, 100V reaches mechanism was analyzed.
