Benefits of Electroless Nickel Plating

[@salvatorehayes2753]

So Does Nickel Plating Provide Better Heat Protection Than Ceramic Coatings? Im Gonna Try Out This Nickel Plating Mainly Becasue My Ceramic Coated Piatons Appear To Be Fadding / Burning Off And The Carbon Build Up Was Pretty Substantial I Feel. These Pistons Had About 20,000 Miles And Engine Us A Turbo 100HP Per Cylnder Engine. Im Hoping The Nickel Works Just As Good As A Thermal Barrier, Stay On Longer And Since Its Alot Smoother Resist Carbon Build Up.

Hi Sir, I heard coating based on electroless is more durable than electrolytic plating. May I know the reason why?

[@DMX-PAT]

Is electroless nickel expensive? Is there anything better in your opinion than electroless nickel?

[@etusch]

uncoated is used one and coated one is brand new. I would prefer to see both used at similar circumstances.

good info thanks!

Well no, nickel has horrible high temperature properties, it's very very soft, becomes even sodter at relatively low emperatures for metals. It is in stainless and inconel but to soften the alloy to prevent cracking or brittle fracture. Now that doesn't mean it isn't a good coating for a piston, but it means the reasons why, aren't what you think they are. Additionally carbon is an element in high allows and it's very brittle great for hardness, chromium again very brittle great for hardness found in stainless and inconel, as well as iron which is soft an malleable, manganese etc.... alloys are about all for the alloy elements working together so to single out one is a bit silly. Now I would be intrigues to know why a nickel coating on a piston is a good thing? Is it just because it's throws out heat better than the ally it's coating? is it just as useful on the older ferrous pistons?

Not sure what you mean when you say that "nickle has horrible high temperature properties." It's melting point is relatively high at 2,651F. The micro hardness HV value from electroless nickle can reach 1,000, similar to hard chrome plating, so its far from soft. In addition to the reasons outlined in the video, electroless nickle plating delivers one of the most corrosion resistant surfaces available. When an aluminum alloy is subjected to elevated temperatures and oxidation and corrosion occur, aluminum oxide is formed. The nickle plating eliminates to formation of this brittle and abrasive oxide.

I mean it has horrible high temperature properties. 2650F isn't particularly high, Are you talking brinell Hardness? 1000 isn't particularly hard, for metals and alloying materials. As far as it's corrosion resistance, yeah it's ok, but so is aluminium, both form oxides, that is what prevents further corrosion from forming the oxide protects the materials, same with stainless steels. Now is the nickel useful as a coating, maybe.. I didn't claim it wasn't, but as I said it's not the wonder material you're making it out to be. go talk to a metallurgist.

dude your obviously not talking about nickle , nickle is not soft , you have obviously never worked with nickle , it may soften metals in alloys im not sure of that but i have used nickle before and fyi the fires of hell cnat melt nickle you need an oxy flame or an arc to do it

[@tangles01]

I'm definitely talking about nickel.

[@NOBOX7]

tangles01 what ever dude , nickle and copper are the same in your eyes i guess becuase copper is a soft metal , nickle is not soft read this wise ass{{{{Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is{{{{ hard}}}} and ductile. ]]] so maybe your confused
