Treatments and coatings

FOR HIGH PERFORMANCE PISTONS

Special treatments for improved performance.

When special high heat and stress resistance, low friction coefficients and high durability are required we can provide several special treatments.

The Racing Division works hard to give the technical answer for the demand of maximum power. We engineer solutions for racing MX, karts and Street bike racing world.  


Molybdenum Disulphide
Low friction. Easy run-in.

Thanks to our internally developed special machine for disulphide spray and screen sprint coating, we can provide with Molykote 7409 coated pistons. This treatment guarantees improved wear resistance in the critical run-in process. A thin layer of MoS2 on the piston surface helps the adjustment of the piston/cylinder interface during the break-in period.

Semi-hard anodic Oxidation
Hardening.
Low Friction.

Anodization (also called anodic oxidation) is a non-reverse electro-chemical  process creating a protective layer of Aluminium Oxide on the surface of the piston. The treated material is subject to a real transformation: the metal reacts with Oxygen at the anode side during electroplating and develops alumina. The coating generated by this process is a surface hardening that reduces friction and wearing-out.

On piston's head

Coatings on head have the aim to harden the crown and create a protective barrier to resist to critical blasting temperatures

On ring's grooves

Rings grooves are coated with semi-hard oxidation to reduce the possibility of micro-welding between ring and the Aluminium groove and to prevent from scuffing.

On pinhole

The hardening of the pinhole boss  with the oxidation allows a better pin's oil lubrication and reduces the risk of the pin's seizure.

On all piston surface

Oxidation on all piston's surface helps to prevent skirt's wearing out and improve smoothness.

Ceramic
Thermal barrier.

Ceramic coating  is applied in order to create a thermal barrier protecting the top and all the piston from thermal transfer and extending its life in the engine.

Under-crown thermal barrier 

The thermal barrier performed by ceramic on piston's head is an advantage for the under-crown too: lowering the inside temperature helps to reduce oil combustion to protect and give longer life to bearings and bushings. 

Tin plating

Low friction.
Easy run-in.

Applied on  all piston surface to allow a low friction running and an easy run-in at engine starting phase.

Combined treatments
Multiple protection

Combining more coatings and treatments altogether adds multiple benefits to the pistons and improve piston's life and resistance especially in high stress and racing engines.
