Science, Maths & Technology

Electroplating

A process used to apply a coating, via electrolysis, from an electrically conductive base material to the object to be coated. Often used to silver plate cutlery and other decorative objects.

Science, Maths & Technology

Shot blasting

Shot blasting entails the forceful direction of abrasive particles against the surfaces of metal parts to remove contaminants or condition the surface for subsequent finishing.

Science, Maths & Technology

Shot peening

Shot peening is a method of cold working in which compressive stresses are induced in the exposed surface layers of metallic objects by controlled impingement of shot.

Science, Maths & Technology

Nitrotec process (oxygen enhanced nitriding)

The Nitrotec process consists of nitriding (nitrocarburising) components, before immediately subjecting them to rapid oxidation, then quenching, finishing with the application of a protective sealant. Oxidation gives protection against corrosion, whilst the quenching and sealing give enhanced surface wear resistance and increased yield strength of materials.

Science, Maths & Technology

Ion implantation

Within a vacuum chamber, surfaces to be hardened are bombarded with a high energy stream of ions that penetrate the surface. This is not a diffusion process. Once impregnated into the surface, the ions (usually carbon or nitrogen) lose their energy and stop moving. The compressive stresses generated in the surface layers improve mechanical and fatigue properties, as well as corrosion and wear resistance.

Science, Maths & Technology

Induction/flame hardening

Induction hardening involves using induced electrical currents to very rapidly generate heat via hysteresis, usually in a workpiece made from medium to high carbon steel. Flame hardening uses oxy-fuel burners to heat the workpiece via conduction. Both procedures use quenching after heating, often followed by tempering and/or stress relieving.
