Black oxide is a conversion coating that is used for appearance and to add mild corrosion resistance and minimize light reflection. It is used for ferrous materials, zinc, copper and its alloys, silver solder and powdered metals. Black oxide is impregnated using oil and wax to achieve maximum… View Full Term

Welding is the process of joining two or more materials (mostly metals) using intense heat. Improper welding techniques can result in defects that...
The stress concentration factor (Kt) gives a clear indication of the amount of overstress at a specified location, which is used by engineers to determine the maximum expected stresses and make informed decisions.
In the realm of high-pressure bolting, it is important to understand the dynamics and behavior of fastener systems under load, and how thread engagement is dangerously compromised by nut oversizing.
