Induction hardening technology employs a refined control setup, with magnetically induced energy patterns acting as a contact-free heat treatment mechanism. A hardening profile is established by the induction station’s electrically manipulated magnetic fields. Science-based principles now gain traction, but what criteria are we hinting at here? A detailed analysis is required to understand the effects […]
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 and case hardening technology. Processing […]
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 oxide failure does occur, so […]
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 issue. Worryingly, if left unchecked, […]
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 extend the lifespan of the […]
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 steel, but how does it […]
Gears and wheel sprockets are low profile components, but that understated physical form belies an innate knack for handling near unendurable loads. Geometrically detailed, these essential mechanical parts are machined from the finest materials. Manufactured, machined, and balanced, the parts are then heat treated so that they can tolerate high loading factors. Flame hardening is […]
High tolerances rule hot and cold precision straightening work. The factory floor is filled with high-tonnage presses and industrial grinding stations, the larger-than-life tools that enable expert material engineers to meet any deadline.
When troubleshooting heat treatment imperfections in vacuum ovens, the undesirable results that stymy production engineers don’t always fall into convenient pigeonholes. Fortunately, the discolouration of metal parts that have undergone this property-manipulating process is a readily identifiable issue.
Flame hardening operations extend the operating life of alloy-rich components by adding rigid strength to the microcrystalline backbone of the heat-treated part.
