Thermal Spray Aluminium Coating

Thermal Spray Aluminium Coating

Thermal Spraying of Aluminum or Aluminizing involves deposition of Aluminum of 99.5% purity over the prepared surface. The sprayed metal is melted by using Electric Arc that is atomized with compressed air and projected over the substrate, and is prepared using Sand & Quartz Blasting. According to the IS & BS Standards, it would be resistant up to 950℃ temperature.

The Aluminizing process is used to protect parts operating in high temperature environments against corrosion and oxidation. As a result, the most common parts coated are high temperature industrial chimney and muffler.

Applications

• Industrial chimneys & muffler in Cement plant, oil & gas refineries or pipelines
• Railway Bridges are aluminum metalized for corrosion protection as per Indian Railway Standard.
• Ship hulls are aluminum metalized periodically for corrosion protection as per IS & BS Standard.

Standards of Process

• BS: 2569 Part I & II
• IS: 2590
• IS: 5905
• BS:1475

Advantages:

• Long term protection
• Better surface preparation
• No size limitations
• Pure aluminum coating
• Onsite jobs possible
• Ideal surface for painting
