Hot Sale Yttrium Oxide Y2o3 for Thermal Spraying
Product description
Laser quenching process parameters are a key link in laser heat treatment. The process parameters mainly include laser power, laser beam scanning speed, focal length of the focusing mirror, and defocusing amount (distance between the quenched surface and the beam focus). The energy absorbed by the quenched surface depends on the laser power; The action time of the laser beam on the quenched surface depends on the scanning speed; The size of the spot depends on the focal length and defocusing amount of the focusing mirror; The laser power density depends on the laser power and spot size. Generally, an increase in laser power results in an increase in the depth of the quenched layer; The scanning speed increases, and the depth of the quenched layer decreases; As the defocusing amount increases, the size of the light spot increases, and within a certain range, the width of the quenching layer increases.
