    MD_76_LIMITED Trust the process...

    Does anyone get their engine parts coated with materials such as this:

    ?

    I was contemplating doing so for my rebuild. Does anyone have any advice/comments regarding any possible cons (aside from $$) by doing this?


    Do you think it would make hypereutectic pistons slighty more detonation-tolerant?

    This a post from an earlier thread started by Jim Burek on coated cams & bearings that I replied to. i cannot answer as to if it will help keep the hypers living longer. The coatings will reduce friction and heat soak if applied properly.

    Steve,
    I did my own main rod bearingss, oil pump gears and lifter bodies (exterior body only) and pistons with DFL. Also ceramic coated the piston crowns after massaging them.

    Techline coatings sells water based DFL and Ceramic coatings for internal engine components as do other vendors.

    To do this you need:
    CLEAN compressed air @ 40 psi
    Small touch up gun
    Coatings
    Acetone or other non petroleum based cleaner (see supplier spec)
    150 grit aluminum oxide media
    small media blaster
    Oven capable of holding your components and baking to 350*F.

    Do not use solvent based coatings in any oven that you will prepare food in.

    Basic overview:

    Prepare the surface such as as any polishing and metal removal.
    Clean the material
    Lightly blast the material to be treated with aluminum oxide
    Clean the material
    Spray the product
    Air cure
    Heat treat in the oven.

    If you are not interested in the DIY method Jim Burek and several other vendors perform this service.
