Repair equipment for metal components

Abstract

This invention relates to a metal component repair device, comprising a cold gas dynamic spraying device. The device includes a powder feeder for providing powder repair material, a gas supply unit, a gas heater for heating the gas, a gas flow controller, and a nozzle assembly for accelerating the powder repair material particles. The cold gas dynamic spraying device is connected to the gas flow controller via the gas supply unit to input a carrier gas. The gas flow controller controls the pressure of the pressurized carrier gas and distributes the pressurized carrier gas to the powder feeder and the gas heater. The powder feeder and the gas heater are connected to the nozzle assembly, allowing the powder repair material to... Particles are accelerated by pressurized carrier gas through a nozzle assembly. The accelerated carrier gas and powder repair material are sprayed from the nozzle assembly onto a repair surface area of ​​a repair component. The cold gas dynamic spraying equipment supplies the carrier gas to the gas supply device and sets a predetermined pressure on the gas flow controller to apply to the carrier gas. A predetermined temperature is set on the gas heater to apply to the pressurized carrier gas and the powder repair material. The spraying distance from the nozzle assembly to the repair surface area is adjusted to a predetermined distance. The powder repair material is cold-sprayed onto the repair surface area through the nozzle assembly to form a coating with a predetermined thickness and predetermined size to cover the repair surface area.
