Alternator caps, engines, crankshafts, pistons, valves, injectors and synchron rings are just some of the parts that benefit from improved wear resistance and corrosion protection after having coatings applied to them by thermal spraying.
Flame Spraying with Wire
Improved corrosion and wear resistance is achieved when coating non-ferrous metals using flame spraying with wire. It’s particularly effective on high-strength steel in car transmission components.
Of all the fuel gases used, BOC recommends acetylene-oxygen as it has the highest flame and achieves the highest melting rate, thereby improving productivity.
High Velocity Oxy Fuel Spraying
HVOF provides improved finishes in areas where good wear resistance is vital, such as crankshafts, pistol rings and engine parts.
The Cold Gas Dynamic Spraying method produces spray coatings that are virtually oxide and porosity free. In the automotive sector, it’s commonly used on electrical components and components of electric engines.
