Bond Laser Passivation vs Chemical Methods
Passivation Treatment with Alfa Laser Cleaning Machine:
What is Passivation?: Passivation is a critical process that enhances the corrosion resistance of stainless steel. Traditionally, this involves chemical treatments that impact the entire product.
1. Chemical Passivation:
Process: Chemical passivation involves using specialized acid formulations to create a protective oxide layer on stainless steel surfaces.
Purpose: Contaminant Elimination: It removes free iron and other surface contaminants. Oxide Layer Formation: The process facilitates the formation of a passive chromium/nickel oxide layer, acting as a protective barrier against future corrosion.
Advantages: Uniform and Stable: The resulting passive film is tenacious, uniform, and stable. Corrosion Resistance: Stainless steels owe their exceptional corrosion resistance to this invisible protective layer.
Industry Applications: Chemical passivation is widely used in food, beverage, dairy, pharmaceuticals, cosmetics, and cannabis processing.
Chemical Equation: The reaction during passivation: 4Cr + 3O₂ → 2Cr₂O₃. This protective layer prevents oxygen and moisture from reaching the underlying iron, effectively preventing rust and maintaining surface quality.
Laser Passivation Treatment:
Targeted Approach: Alfa Laser Cleaning Machine’s technology specifically targets areas of the surface.
How It Works: Alfa’s laser solutions concentrate on the topmost layers of the substrate in precise locations. High-intensity laser pulses hit the targeted surface, causing the top few microns to remelt and restructure into a corrosion-resistant surface. The resulting oxide layer acts as a barrier against corrosion, preventing it from occurring and compromising the treated area.
Benefits: Ideal for Lightweight Materials: Alfa’s laser passivation is well-suited for lightweight components. Bonding Preparation: It ensures sealed components (e.g., batteries) are corrosion-resistant.
Saltwater and Atmospheric Resistance: The treated surface can withstand harsh environmental conditions.
Enhanced Bond Strength: Laser passivation creates stronger bonds and extends their lifespan.
Quality Improvement: The process improves the overall quality of the treated area.
Cost-Effective: Compared to traditional chemical passivation methods, Alfa’s laser approach offers cost savings.
3. Buffing and Mark Removal:
Laser Cleaning Systems: Alfa’s systems are versatile and effective for various tasks, including buffing and removing marks and abrasions.
Supported Materials: Stainless Steel: Alfa’s laser cleaning can efficiently remove rust, oxide layers, and contaminants from stainless steel surfaces. Other Metals: It’s also applicable to steel, aluminum, copper, and brass.
4. Applications with Alfa Laser Cleaning Machine :
