When it comes to piston coatings, there’s lots of stuff that people think they know and lots of stuff that’s just flat out wrong. In this video you are going to learn all you ever wanted to know about piston Coatings with MAHLE Motorsport. The chat is about what coatings do, what coatings do not do, what the differences are between the intentions and purposes of coatings, and how they deal with the stresses that they are placed under inside the engine.
Piston coatings are nothing new and what’s interesting is that MAHLE as one of the OEM leaders in piston manufacturing has been at the forefront of piston coating technology and applications. This video isn’t just a basic overview. We kind of take a step by step “tour” of a piston and learn about the different coatings as well as the different jobs those coatings perform. What’s being done with the ring grooves is a lot different than what’s being done with the piston skirts. That same statement can be made with what’s happening with the crown of the piston as well.
If you are going to be ordering pistons for a build soon, this is good information and a good topic for you to consider when making that buy.
