Workpiece hardening is a central part of any heat treatment facilities’ work output, so it’s only logical that several alternative techniques should develop in response to this need for mechanical toughness. Let’s compare two of these popular hardening techniques. Essentially, we’ll be noting the differences that exist between induction hardening […]
A black oxide finish imbues a worked ferrous component with an attractive ebony coating. The process transforms a thin layer of surface metal into iron oxide, so no deposits are called for here, just a chemical reaction that enhances corrosion resistance. As advantageous as this supplementary feature undoubtedly is, black […]
Large-scale engineering projects use machined metal components to support structural loads. They accomplish this task by accessing the strength of a selected alloy. Unfortunately, strength isn’t the only attribute contained within the metal. The worked part also contains undesirable properties, those incurred by numerous machine stations. Residual stress is the […]
Hot die materials are burdened with a formidable task, which is an elaborate way of saying high temperatures and higher pressures are at work. The forging process applies compressive force and heat to the tools used in forging processes, so deformation stress is a major issue. Fortunately, heat treatment techniques […]
As we discuss carbonitriding, expect to be carried through a heat treatment process that relies heavily on the control of local atmospheric variables. In particular, as the label implies, carbon and nitrogen atoms are injected into the controlled environment. Undoubtedly, this is an essential technique, one that surface hardens base […]
