Moulds are hollowed-out blocks that are used as tools for the mass production of parts such as plastic bottles and automotive parts. These moulds are expensive to manufacture and are therefore designed to have a long service life.  Manufacturing industries thus seek cost-effective processes to...

One of the barriers to increasing microprocessing clock speed is the extreme difficulty to move heat out of the CPU chip. Wits researchers have developed a cold spraying heat exchanger manufacturing technique where thin layers of copper and aluminium are deposited on a copper substrate. De-alloying...

Tungsten carbides coatings are used in drills and cutting tools to provide a desirable operational lifetime of the coatings in use, as they have enhanced mechanical and wear properties. They are typically deposited using thermal spraying techniques. Tungsten carbides deposited using these techniques...
