Title:
METHOD AND APPARATUS FOR SURFACE COATING
Document Type and Number:
Japanese Patent JPH01198461
Kind Code:
A
Abstract:

PURPOSE: To uniformly and efficiently coat the wide area of a base material by thermal spraying by applying arc melting to two band-shaped metallic bodies, crushing the resulting molten metal in a compressed jet stream, and then allowing the pulverized bodies to fly.

CONSTITUTION: Band-shaped metallic materials 1, 1 ' are fed to a head part 17, and these are melted by means of arc discharge directly after passing through the head 17. Air A from an air compressor is introduced into the head part and formed into a high-speed jet stream JA, which is converged on the front side of the arcing point 40, in the close vicinity of this point 10. The molten metallic-material flows 1, 1 ' are sucked into the compressed jet stream and crushed into pulverized bodies, and these pulverized bodies are allowed to fly rapidly and thermally sprayed on the surface of a base material to coat this surface. By this method, the thermal spraying of low-melting metals, such as Zn, Al, and alloys thereof, can be carried out with high workability.
