Problems solved by technology

However, for spraying thicker coatings or spraying gradient coatings, as well as coatings with different performance requirements and different materials, it is not suitable for coatings. It is necessary to spray multiple times or readjust the specification parameters every time the material is changed to ensure the coating. The quality and the requirements of coating performance are not only cumbersome in the spraying process, but also a waste of resources and energy, and the spraying efficiency is also very low

Abstract

An integrated double-head electric arc spraying equipment and a spraying method relate to an electric arc spraying equipment and a spraying process. The wire feeding reel (4) of the present invention is arranged on the wire feeding mechanism (5), and the spraying power supply (2) and the control cabinet (11) are connected by a No. 1 control line (3) and a No. 1 output cable (12). The control cabinet (11) and the double-head spray gun (7) are connected by the No. 2 air compression tube (10), and the wire feeding mechanism (5) and the double-head spray gun (7) are connected by a cable and a wire guide tube (6). connected. The pressure of compressed air for spraying is 0.6-0.8MPa. The spraying voltage is 20-35V. The spraying current is 50-300A. The invention reduces spraying procedures such as refueling and adjusting process parameters, saves spraying time and improves spraying efficiency. It is possible to make mosaic layered coatings of different materials and performances at the same time, such as the thick layer of the substrate being Ni 3 Al, the mosaic thin layer is WC. It has the outstanding advantages of fewer spraying processes, high spraying production efficiency, and energy and resource saving. The spraying method of the present invention has the advantage of being simple and easy to operate.

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...
