Plasma nitriding is a surface modification process used to enhance the hardness, wear resistance, and fatigue life of metals by introducing nitrogen ions into the material's surface using a glow discharge plasma. This technique is favored for its ability to produce uniform and controlled case depths without significantly altering the dimensions of the treated components.

Enhance the hardness

Wear resistance is the ability of a material to withstand damage or degradation due to mechanical action such as friction, abrasion, or erosion. It is a critical property for materials used in applications where surfaces are in relative motion, impacting longevity and performance.

Wear Resistance

Fatigue life is the number of stress cycles a material can endure before failure occurs, typically due to the gradual accumulation of damage under cyclic loading. It is a critical factor in engineering design, particularly for components subjected to repeated stress or strain over time.

Fatigue Life

Metals are elements characterized by their high electrical and thermal conductivity, malleability, ductility, and a lustrous appearance. They are typically solid at room temperature and are used extensively in construction, manufacturing, and technology due to their strength and versatility.

Material's surface

Glow discharge plasma is a type of plasma formed by the passage of electric current through a gas at low pressure, where the gas becomes ionized and emits light. It is widely used in applications such as material processing, lighting, and analytical chemistry due to its ability to efficiently generate ions and radicals in a controlled environment.
