Plasma Nit®

Unique Service of ion nitriding in Monterrey,Mexico:

Is a vacuum gas nitrided by assisted plasma that produces surface

hardness in steels by forming nitrides with: Fe, Cr, Mo, Mn, V, Al and Ti.

Metalic mechanisms, molds and tools: Where the operation involves a gradual deterioration or damage of the solid surface Caused by the removal or displacement of material By the mechanical action of a solid, liquid or gas in contact.

Examples:

Recommended steps to anticipate the type of wear that our metal component will be subject

1. Analysis of the type of surface damage;

Wear categories classified by the type of relative motion found

2. Study of the mechanical requirements (hardness, toughness, strength). 3. Selecting the type of steel. 4. Defining variables of the hardening heat treatment, tempering and stress relieving. 5. Surface Optimization with PlasmaNit ®.

1.Source of active nitrogen. 2.Temperature. 3.Time. 4.Nitrides forming elements in the steel (Fe, Cr, Mo, Al, V, W).
