A hardness test in which a ball shaped indenter (normally 10 mm in diameter) is pressed into the material to be tested by a specified load ranging from 500 to 3000 kilograms. The diameter of the resulting indentation in the tested material is measured and this dimension is converted to a Brinell Hardness number using [...]
The primary objective of the annealing heat treating process is to soften a part or component. Annealing is performed by heating to a specific temperature, holding at that temperature for a specific time, then slowly cooling to room, or ambient, temperature. Temperature and time vary depending on the metal or alloy. Many industrial metals become [...]
Abrasive wear is a cutting process. This may seem counter-intuitive since most perceptions of cutting require a tool, such as a scissors, chisel, or machine tool. Abrasive wear, however, is cutting on a microscopic scale. The “tool” is either contaminant particles from an outside source, or a mating component. Wear of mining or excavation machinery [...]
The automotive industry takes durability testing seriously. They cannot afford to do otherwise. If defective parts enter the assembly stream undetected, a lot of vehicles may be built and sold before the ultimate durability testers, car buyers, expose the problem. Engines undergo extensive dynamometer testing lasting weeks or even months. This testing continues in order [...]
