[edit]The section of the article talking about development for rotary engines makes no sense. Rotary engines have an impeller or rotor, not pistons. So the comment about pistons in a rotary engine is nonsensical, unless talking about a circumferential piston engine (which is not what the author appears to be referring to).

The page could do with a more approachable opening sentence. I think even rocket scientists might be baffled at the current opener: "Nikasil is a trademarked electrodeposited oleophilic nickel matrix silicium carbide coating..." Call me uninformed, but the only words I understood from that description were "trademarked and coating." I'll have to look up "nickel matrix." —Preceding unsigned comment added by Broncostar (talk • contribs) 04:05, 18 May 2008 (UTC)
What are its advantages?
[edit]The article does not state what the advantages of Nikasil are. Does it eliminate cylinder liners? Does it make an engine lighter? Is it bester for cooling in heat transfer? It is all very vague94.193.157.106 (talk) 15:30, 15 March 2015 (UTC)
- It gives the wear advantages of a cylinder liner with better thermal performance than a cylinder liner. Liners are generally poor thermally, because their interface to the block has poor thermal conductivity across the junction. Some air-cooled aircraft engines go to extreme lengths during manufacture to get a good contact here - affordable for aircraft, but not for cars. Secondly the use of a dry liner requires a thicker block for mechanical strength, as two layers each need to be strong enough to support themselves. With Nikasil there's no extra thickness needed.
- The metallurgy is also good (in terms of long term wear) - it's better than most steel liners would be. Andy Dingley (talk) 20:42, 15 March 2015 (UTC)
Error in article references
[edit]The link in the First paragraph "initially developed to allow rotary engine apex seals" links to the wrong reference. It should be the Wankel Engine reference not aircraft rotary engine. — Preceding unsigned comment added by 192.139.221.50 (talk) 19:58, 20 December 2018 (UTC)
Lipophilic?
[edit]Lipophilic means fat-loving, as in substances miscible with non-polar molecules. Possible wrong word for this article.Longinus876 (talk) 07:27, 18 November 2020 (UTC)
