Moly Spraying

Moly Spraying

Moly spraying is a process used to increase the wear resistance of our aluminium castings. ‘Moly’ is the shortened name for molybdenum – a silvery-grey metal that has the sixth highest melting point of any element (2623°C). When added to various alloys, it increases the strength and wear/corrosion resistance of the resultant materials.

The applications for moly spraying

Molybdenum’s ability to withstand extreme temperatures makes it ideal for use in aerospace and defence parts. Molybdenum was used extensively in armour plating and tanks during the First World War and is now used in industrial applications – often replacing chromium plating and other techniques.

At Haworth Castings, we use moly spraying for castings that are destined for high-end aerospace applications – where the parts often need to withstand adverse weather conditions and temperatures.

The benefits of moly spraying

The benefits of this process include:

• Reduced friction and wear (thus providing longer life parts)
• Lower abrasion on any mating parts
• Ease of penetration and bonding to metal surfaces
• Excellent corrosion and chemical resistance
