Plasma nitriding, also called ion- or glow-discharge nitriding, is an advanced surface-engineering technique that allows for treatment of many different engineering components made of ferrous and titanium alloys.
Precise heat control is essential in temperature-sensitive applications. Even small deviations from the setpoint can result in defective or rejected products. Despite this, many facilities for heating or melting metals or glass, as well as annealing, drying and countless other applications, still burn fossil fuels. This makes maintaining precise temperature control challenging. It also produces significant emissions, meaning that it is incompatible with a move to net-zero carbon emissions.
Rockwell testing is the most commonly conducted hardness testing. The testing procedure is simple, and the readings can be directly attained from the testing machine.
We typically start the New Year off by focusing on new technologies throughout the thermal-processing industry in our January issue. With that in mind, let’s begin 2023 by looking at some interesting technological developments that have come across my inbox in the past nine months.
