Arc spraying is a method that arcs are generated between two wires that are connected to the positive pole and the negative pole of the power source. The heated molten part is atomized by the compressed air jet and sprayed onto the substrate to form a coating.Since this method is only suitable for spraying wire, so also known as arc wire spraying.
一. The characteristics of
(1)the spraying material must be conductive.
(2)the arc temperature is lower than the plasma temperature, but higher than the oxygen acetylene flame temperature.The compressed air pressure of atomized wire can be high, so the spraying layer is relatively dense.
(3)since two wires are sent in at the same time, the spraying efficiency is high.
二. use
It is suitable for the spraying of large shafts and rollers as well as the long-term protection of large structural parts.
