A METHOD AND SYSTEM FOR DIE COMPENSATION AND RESTORATION USING HIGH VELOCITY OXY-FUEL SPRAY COAITNG AND PLASMA ION NITRIDING

摘要

The present invention relates to a method of correcting and regenerating a mold using a high velocity oxy-fuel coating method and a plasma ion nitriding method, and more specifically, to a method of correcting and regenerating a mold using a high velocity oxy-fuel coating method and a plasma ion nitriding method which can correct and regenerate a specific portion (damaged portion) of a press mold generating a fine curve at a door of a vehicle, and the like to an original condition. Thus, the present invention is to provide an efficient method of correcting and regenerating the mold using the high velocity oxy-fuel coating method and the plasma ion nitriding method which can improve wear resistance and fatigue resistance and increase mold overlay efficiency at the same time by providing a stacked thickness quantification technology in which the damaged portion of the mold generating the fine curve at the door of the vehicle, and the like is precisely corrected in a circular shape by the high velocity oxy-fuel (HVOF) coating method, and hardening a surface of the mold by nitriding the surface of the mold using the plasma ion nitriding method after the surface is coated by the high velocity oxy-fuel coating method.
