Kemet has a full process programme which includes diamond slurries for both twin plate and open face lapping systems, Kemet composite plates for specific types of ceramics as well as specially formulated cast iron plates

Hardness testing has long been one of the most widely used testing procedures conducted on a huge variety of applications ranging from university laboratories for research purposes on new materials to large manufacturers of automotive and aerospace components where standardised material properties are key to the success or failure of a particular component or sub assembly. Coatings and case hardness treatments also need to be able to prove they are as hard as specified, and that the depth of the hardened structural layers match the intended application.

Cleaning and surface preparation are critical for perfect quality of finished parts and selecting the right process has never been so important as customers seek better quality and performance for their coatings. Several parameters are involved and it is important to consider all the various options to get the best ultrasonic cleaning process. The formulation of a detergent takes into account the substrate specifics as well as the impurities to be removed from the surface. The steps before and after the cleaning process are also critical to defining the process. Even sensitive metal parts can be safely and efficiently cleaned in a water-based cleaning system without damaging the substrate and without using problematic solvents.
