Problems solved by technology

In this way, the ferrite and martensite components on the surface are transformed into austenite, and the strength of the formed surface layer is improved by nitrogen through solid solution strengthening. However, the disadvantage of this technology is that it is difficult to control the furnace temperature and infiltrate the material. Nitriding layer will appear reticular, co

Abstract

The invention discloses a laser shock method. The method comprises the following steps: (A) providing a laser shock device and a vacuum ion plating machine, wherein the laser shock device comprises a computer control system, a high-power laser, an automatic water sprayer and a worktable, the worktable is equipped with a first fixture and the vacuum ion plating machine is equipped with a second fixture; (B) covering an aluminum foil absorbing layer on the surface of a metal material; (C) controlling the automatic water sprayer to spray water to the surface of the aluminum foil absorbing layer by means of the computer control system; (D) controlling the worktable to move by means of the computer control system; (E) controlling the high-power laser to emit laser beams to the aluminum foil absorbing layer by means of the computer control system; and (F) finally removing the aluminum foil absorbing layer, placing the metal material in the vacuum ion plating machine and forming a graphite coating on the surface of the metal material by utilizing a physical vapor deposition method. By utilizing the laser shock method, surface strength and hardness of the metal material can be improved and cavitation erosion can be effectively avoided.

Description

technical field [0001] The invention relates to the field of laser shock strengthening, in particular to a laser shock method. Background technique [0002] The surface strength of the aluminum alloy volute of the aero-engine fuel supply system decreases due to cavitation. There are fatigue cracks and erosion morphology on the surface of the cavitation zone, and the material is damaged and destroyed under the combined action of cavitation and erosion. When the hydropower station operates under load conditions, cavitation problems will also occur. Holes, gaps, and shedding will appear on the blades of the turbine, which will damage the flow-through parts of the turbine. The unit will generate a lot of noise and vibration at the same time. The output and efficiency of the turbine reduce. Vibration cavitation with a large area of ​​irregular corrosion will appear on the surface of the bearing under working conditions. Therefore, cavitation is also an important form of damage ...
