Abstract

The invention relates to a kind of arc spray device and spraying technology. A carrying wire plate is on the wire feeder of the device. Electric source for spraying connects to controlling box through size 1 controlling line and size 1 electric output cable. The controlling box connects to the double-spout spray gun through size 2 air-compressed tube. The wire feeder connects to the double-spout spray gun through electric cables and wire duct. Pressure of compressed air for spraying is 0.6Mpa to 0.8Mpa. The eclectic voltage for spraying is 20V to 35V .The electric current for spraying is 50A to 300A. The invention eliminates steps such as renewing painting material, adjusting technical parameter and so on .So it can save spraying time and raise working efficiency .The invention can be used to make mosaic laminating layers of different material and different performance, for example, thick base Ni3Al layer with thin mosaic WC layer .The invention has prominent advantages such as simple spray procedure, high spray efficiency, saving energy and resource and so on. The spraying method of this invention can be operated easily.

Description

Technical field:

[0001] The invention relates to an electric arc spraying equipment and a spraying process. Background technique:

[0002] Arc spraying is to melt two wires as electrodes through a short circuit, atomize the molten metal through compressed air and spray it onto the surface of the workpiece at high speed to form a coating. Compared with other spraying techniques, arc spraying has obvious advantages: ①The coating can achieve high strength and excellent coating performance. High bonding strength can be obtained without increasing the temperature of the workpiece and without using expensive primer materials. When spraying aluminum bronze, the self-adhesiveness of the coating is present, which further improves the bonding strength, and the bonding strength can reach 30MPa, which is generally 2.5 times that of the flame sprayed coating. ②The spraying efficiency is high, that is, the weight of the sprayed metal per unit time is large. ③ The energy-saving effect o...
