The Heat-Affected Zone (HAZ) is one of the most critical aspects of welding metallurgy. It's the area of base metal that is not melted but has undergone significant changes in its microstructure due to ex.......
If the door lock is a zinc alloy material, its hardness and rust resistance are very poor, that is, thick plating is easy to fade and blacken and rot and blister, but its advantage is that it is easy to m.......
