Purpose:

1. Wear resistant and protective coatings

Chromium nitride is widely used for surface protection of industrial components due to its high hardness (HV1800-4000), low friction coefficient (0.20-0.30), and excellent wear resistance

Molds and Tools: Used for plastic molds, cast steel molds, metallurgical molds, etc., significantly extending their service life and reducing maintenance needs caused by wear and tear. Cutting tools: such as drill bits, milling cutters, etc., improve cutting accuracy and durability, and adapt to high load machining environments. Precision parts, such as robot joints and medical device components, are coated to reduce friction loss and enhance corrosion resistance.

2. Hard alloy and powder metallurgy

Chromium nitride is used as an additive or reinforcement material to enhance the performance of composite materials

Hard alloy: combined with materials such as tungsten carbide, used to manufacture wear-resistant cutting tools, mining drill bits, etc. Powder metallurgy: As a reinforcing phase, it improves the strength and high temperature resistance of metal based composite materials.

3. Steelmaking and Alloy Industry

Steelmaking additive: Chromium nitride can partially replace nickel in stainless steel, reducing production costs, but cannot completely replace nickel's corrosion resistance. High temperature structural material: used for high-temperature resistant alloys, such as aviation engine components, due to its melting point of up to 1650 ℃ and excellent stability at high temperatures.

4. Electronic and Optoelectronic Materials

Conductive thin film: Chromium nitride coating is used as a conductive layer for electronic components to enhance oxidation resistance.

Semiconductor equipment: used as a protective layer in specific processes to reduce performance degradation of devices in high-temperature environments.

5. Corrosion resistance and environmental protection field

Chemical equipment protection: used for coating the inner walls of reaction vessels and pipelines to resist acid and alkali corrosion.

Environmentally friendly materials: used as corrosion-resistant coatings in sewage treatment equipment or as food contact materials

6. Special functional materials

Antiferromagnetic material: Nanoscale chromium nitride powder is used for sensors or magnetic storage devices due to its unique magnetism.

High temperature refractory material: As a lining material, it resists the erosion of high-temperature molten metal in metallurgical furnaces.

Storage method: This product should be sealed and stored in a dry and cool environment. It should not be exposed to air for a long time to prevent moisture from causing aggregation, affecting dispersion performance and usage effect. In addition, it should be avoided from heavy pressure and not in contact with oxidants. It should be transported as ordinary goods.
