Creation of New Robust Liquid Induction Carburization Technology LINCARB for Deep Internal Splines with High Aspect Ratios

New, patented highly advanced thermo-chemical processing (LINTERPROCESS) and heat-treatment (LINHEAT) technologies were developed by SANOVA to address and solve metal and alloy performance deficiencies. Based on these innovative technologies, SANOVA has designed a treatment process which creates highly durable protective surface layers with strong mechanical properties on outer and inner surfaces of components made from various alloyed, high-strength and corrosion-resistive steels, as well as Ti, Zr and Nb alloys. SANOVA"s LINTERPROCESS and LINHEAT technologies have a distinct advantage over traditional furnace-based treatment processes due to combination of specially formulated and applied highly effective active media and precise control of treatment parameters, and are able to produce desired microstructure and mechanical properties on the gear teeth and deep internal splines with aspect ratio as high as 5:1 and even higher. LINTERPROCESS and LINHEAT technologies are unique and highly effective, while simple to implement and maintain, environmentally friendly and cost-efficient. They employ effective high-frequency induction heating and high pressure of the active medium in working chamber to generate highest-quality results in shortest treatment durations.
