Nitrocarburizing is the most common thermochemical treatment, consisting in enrichment of the surface of ferrous materials with Nitrogen and a small amount of Carbon. The treatment is used to enhance the corrosion and wear resistance and tribological characteristics of parts. There are a few methods of preforming Nitrocarburizing, depending on medium, each with unique advantages. […]

Galling is a form of adhesive wear that is caused by the microscopic transfer of material between metallic surfaces normally during a sliding motion. The friction created tears material from one material and fuses it with the other causing seizure. Tribology of Galling. Galling occurs when the frictional forces are strong enough to cause adhesive […]

Hydraulic cylinders generate linear mechanical force using fluid from an external pump driven by a power unit. Converting mechanical energy into hydraulic energy, moving the liquid through a flow system for a variety of applications, such as pressing, pulling, pushing, or lifting. They are often used in places where heavy loads need to be moved, […]

Traditionally combustion engine cars have used a differential to split the engine torque in two directions at different speeds. Power from the engine runs through a transmission and turns the vehicles axle in one direction. However, with the introduction of Electric & Hybrid Cars there is now another choice that no longer needs a differential. […]

Adhesive wear resistance and low coefficient of friction values are of paramount importance on valvetrain components. ARCOR® represents the latest controlled liquid iconic nitrocarburizing (CLIN™) surface treatment technology. It provides an excellent combination of wear and corrosion protection as well as enhancing friction properties These benefits are widely recognized and specified by engine manufactures to […]

Arcor® is a controlled liquid ionic nitriding treatment, known as CLIN, and is specified when a high-performance surface treatment is needed on brake components. The Arcor® process represents the latest in Liquid Nitriding technology and is available from the global Technique Surfaces jobbing shop network It offers many advantages over the traditional metal finishing processes […]

The HEF Group are globally trusted by manufactures of thread rolling dies to apply controlled liquid ionic nitriding treatments (CLIN). These surface treatments are thermo-chemical diffusion treatments that enrich the surface of ferrous materials with Nitrogen & a small amount of Carbon – both of which are present in the liquid nitriding bath. The Arcor® […]

Did you know the authorization from ECHA (European Chemicals Agency) for Hexavalent chromium (Cr⁶⁺) & Trivalent (Cr0₃) usage in Europe expires in September 2024? Exceptional authorizations are possible under specific demand at ECHA, and the sunset date may be delayed for some applications; However, the aim of the authorization is to guarantee that the risks […]
