Liquid Nitriding
Liquid nitriding or salt bath nitriding improves surface properties like wear and corrosion resistance and anti-galling. The process is widely used for enhancing the performance of oilfield components such as drilling, completion and intervention tools.
Gas Nitriding
Gas nitriding is a case hardening process that involves enriching the ferrous part surface with nitrogen at relatively low temperature. The resultant part will have increased wear and corrosion resistance, surface hardness and fatigue strength with low distortion. Unlike liquid nitriding, this process can be applied to specific locations on a part by masking the unwanted regions. Applications include industrial gears, shafts and downhole tool components.
Induction Hardening
This hardening is carried out using a CNC controlled scanner. Induction hardening provides wear resistance to components manufactured from various alloys. Blue Light has the capacity to induction harden sheaves, pulleys or gears up to 2m diameter and shafts up to 2m in length.
TRIBOX
A specialized heat treatment process for oilfield components that operate for extended periods of time in corrosive environments. The process, which is equivalent to quench, polish, quench (QPQ), provides enhanced corrosion resistance, wear resistance and anti-galling properties.
Carburizing
Blue Light has the equipment and techniques to carry out pack carburizing and gas carburizing to harden steel and alloy steel components. The process produces a thin carbon enriched layer of material penetrating into the component surface. This layer is subsequently heat-treated by either quenching, induction hardening or flame hardening resulting in a surface with high hardness and wear resistance.
