Plasma Nitriding is a surface-hardening heat treatment that introduces nitrogen atoms into the surface of steel to form nitrides. The purpose of nitriding is to increase the surface hardness of the steel and improve its wear and corrosion resistance properties. This treatment takes place in a medium (gas or salt) which gives off nitrogen atoms. Plasma nitriding scores over conventional nitriding techniques, namely lower processing temperature, almost zero contaminations, faster treatment cycles, lower cost and replacement of costlier material.

1. No Post grinding operation is required.
2. The process can be more accurately controlled.
3. Can be performed at lower temperatures with less Distortion.
4. Reduced time cycles with eco-friendly process

1. Plasma nitriding is suitable for most of the industrial sectors, manufacturing dies, plastic moldings, extrusion dies, turbine blades and automobile components like gears, crankshafts, camshafts, etc.

Plasma Nitriding is a surface-hardening heat treatment that introduces nitrogen atoms into the surface of steel to form nitrides. The purpose of nitriding is to increase the surface hardness of the steel and improve its wear and corrosion resistance properties. This treatment takes place in a medium (gas or salt) which gives off nitrogen atoms.

Plasma Nitriding scores over conventional nitriding techniques, namely lower processing temperature, almost zero contaminations, faster treatment cycles, lower cost and replacement of costlier material. This process is suitable for most of the industrial sectors, manufacturing dies, plastic moldings, extrusion dies, turbine blades and automobile components like gears, crankshafts, camshafts, etc.

Plasma nitriding has invaded the industrial sector so extensively that because of its advantages has an edge over conventional surface hardening processes and are used in many industrial sectors like:

1. Automobile Industry - crankshafts, camshafts, gears, pistons, cylinders, valves
2. Metal Casting and Moulding Industries - moulds for all types of alloys
3. Forging Industry - all kinds of dies for hammering and pressing
4. Aluminium Industry - dies for casting and extruding
5. Plastics Industry - extruder screws, cylinders, moulds for injection moulding
6. Machine Building - shafts, spindles, slide-rails
7. Powder Metallurgy - gears, bushes, synchromesh rings
8. Power Engineering - turbines, shafts, spindles, gears

1. No Post grinding operation is required.
2. The process can be more accurately controlled.
3. Can be performed at lower temperatures.
4. Less Distortion.
5. Reduced time cycles
6. Eco-friendly process
