Abstract
The invention relates to a far zone plasma spray gun device. The far zone plasma spray gun device comprises an insulating hollow casing and at least two evenly-arranged plasma spray guns. An insulator is arranged between the plasma spray guns. The length of the plasma spray guns and the insulator is less than that of the insulating hollow casing so as to form a plasma discharge region. A plurality of plasma spray guns are arranged in an insulating hollow casing so as to perform gas discharging in a larger area and produce plasma. The plurality of plasma spray guns are evenly arranged such that full-scale and uniform plasma can be produced in the discharge region. According to the invention, the far zone plasma spray gun device can work in a common atmospheric environment. By the adoption of the device, materials to be processed in the far zone can be better treated, and the material surface modification effect is good.
