Magnetism-control spatter and arc source vacuum coating technique and equipment. The characteristics are as follows: it adopts more than two different metals as target material; arc and magnetron sputtering were adopted simultaneously; at least one target material was vaporized by directional industrial arc ion source; workpieces pass different targets in turn while rotating; alloy film and compound film would deposite on the workpiece in inertia atmosphere and reacting atmosphere separately. Advantages are technique novelty, low cost and arc droplet reduction.
