Gas Turbine Repair and Remanufacturing Technology (Micro Arc Spark Deposition Coating, MAD L-MAD)

Innovative technology (non-destructive restoration technology and non-destructive surface strengthening technology)

Micro arc spark deposition coating, MAD L-MAD

The anode rod material can be deposited on the damaged area of the cathode surface under the action of a micro-arc spark. The frequency of the micro-arc spark is 70-400HZ, the duration is 10^-5~10^-6 seconds, and the temperature in the contact area can reach 8000~25000°C instantaneously, and the alloying of the anode to the cathode occurs, resulting in metallurgical bonding, but the working surface There was no significant increase in temperature. The action time of micro-arc spark deposition is only about one ten thousandth of that of laser melting. Although the coating rate of micro-arc spark deposition is lower than that of laser cladding, it prepares the bottom layer and high-hardness surface layer of laser cladding, and solves the problems of laser cladding undercut, removing pores, local cracks and other metallurgical defects in the laser cladding layer. The most effective aid method. The preparation of MCrAlY-based coating on the blade surface is better than the conventional plasma spraying process, and a dense metallurgical bonding coating is obtained.
