Ceramic coatings

Post by T-34 » Mon Feb 09, 2015 12:36 pm

Just found a local mob that do cermaic coating and am thinking of getting my combustion chambers and piston crowns done, they can also do a skirt coating to reduce friction. My engine is blown and this year the budget does not extend to forged pistons so I'm thinking that this could be a good idea. Prices were very reasonable.

Anyone tried this before? I'm interested to hear other people experiences.

If anyone else is interested - here's a link - http://www.pacemaker.com.au/index.php?o ... Itemid=327

I have used them for exhausts , but not internal parts
the service was quick and they called me as soon as the job was ready
( thats hard to find nowadays ---- real service )

I have used internal coatings on all my bikes, since i did my first piston coating in about 99 and noticed a definite difference in engine temp on a 595 daytona , they were hot buggers in traffic , and after coating it took a lot longer to get to that stage
recon its saved a lot of grief over the years with the turbo motors too

even have a funny wall hanging , piston top from one of my motors after the bush fire
i found the spare 750 motor gutted of aluminium, all the head studs supported by the copper gaskets and niccasil cyl liners , valves laying all around complete with springs and seats, and each cyl still had the ceramic piston top with rings pin and rod in order behind it
kept a piston top, scrapped the rest

Thanks guys, great feedback.

Going to pop round there and have a chat with them. Will let you know how I get on.

Iv'e used ceramic crown coatings on most of my small bikes, except the 250's maiden run, holed a piston,,
I'm not sold on combustion chamber coating, the head has to go somewhere, and blocking heat transfer to the water jacket, or cooling fins seems counter productive to me ?

dont know nothing about Ceramic coating piston tops, except for what ive overheard Greg saying in various conversations, :) ,, observation tells me that it depends on what fuels one runs and the dependency of that fuel on combustion temperature, :wink: ,,

An interesting point. My main reason for wanting to do it apart from not running forged pistons is that I have cooked a few valve seats due to excessive heat in the head. The heat seems to become too much for the normal cooling to handle. I figure if I can keep the heat in the chamber and then spit it out the exhaust that would be a benefit - but then would I just be putting extra heat exactly where I don't want it?

Hopefully visiting the coating place this arvo, will see what tech advice they can give me.

I'm sure there are blokes that frequent the Landracing forum who could advise you , experience will outweigh sales pitch every time.
