Plasma Projection
Plasma Spraying – Chromium Oxide (Cr₂O₃)
Plasma spraying of Chromium Oxide (Cr₂O₃) is an effective solution for solving problems of wear, friction, corrosion, and attack in acidic and alkaline environments. This coating is ideal for improving the resistance of parts exposed to extreme conditions. It is particularly used in various sectors, such as the automotive, mechanical, chemical, and petrochemical industries, as well as by pump manufacturers, the energy (thermal and hydraulic) industry, and the food industry.
Benefits
– Improved friction: Reduces friction and extends part life.
– Anti-corrosion: Provides exceptional protection against corrosive environments, whether acidic, alkaline, or alcoholic.
– Suitable for the food industry: The coating is suitable for use in demanding environments, including the food industry.
– Hard coating: Excellent resistance to wear and severe mechanical conditions.
Features
– Frictional wear resistance: Protects parts from the effects of friction and wear under harsh conditions.
– Corrosion resistance: Highly effective against acid, alkali, and alcohol attacks.
– Thickness: From 0.1 to 0.6 mm, providing protection tailored to the requirements of each application.
– Hardness: Up to 1300 HV, depending on the composition of the powders used, to ensure high mechanical strength.
– Surface finish: Rough or Ra < 0.2 µm, allowing for a smooth or textured finish as required.
– Temperature resistance: Up to 540°C, suitable for high-temperature environments.
