Coatings for aluminium
Hi all,
I have an aluminium component about 150mm by 100mm and about 10mm thick which needs a coating with the following properties: 1) 700-1000 VH 2) coeff of friction of about 0.1 - 0.2 3) operating around 200 degrees centigrade intermittent Any advice on possible coatings and ideas on cost would be much appreciated. Regards, bShah | |||

RE: Coatings for aluminium
Hi bshah
![]() To suggest a suitable coating will really require you to give us a lot more information. Quote:1) 700-1000 VHThis does exclude a large number of coatings, but still leaves many coatings to choose from, but this in itself is not a good critera for selection where thermal spray coatings are concerned. Hardness does not always equate to wear resistance or strength very well. Quote:2) coeff of friction of about 0.1 - 0.2This in itself does not mean very much, as environment, couterface material and surface finish are big factors. Quote:3) operating around 200 degrees centigrade intermittentThis is a very important consideration, but again a very large number of different coatings would be OK.

RE: Coatings for aluminium
Hi Gordon,
Thanks for your reponse. In this application a hardness of 700-1000 VH will give enough wear resistance. The coeff of friction of 0.1-0.2 is desirable against a machined aluminium surface in a mildly acidic environment. The component to be coated is also machined aluminium. bshah | |||

RE: Coatings for aluminium
Hi bshah
I'm sure many could suggest coatings that fit your criteria, may be anodising or a thermal spray coating or other. I would not feel comfortable or confident that any of these potential suggestions would in fact be suitable or not for your actual application. Making a good coating selection can be a difficult task even with detailed information of the application. If you are confident in a coating meeting just your property criteria, try looking at a few coating material catalogues and choose a few that match ![]() Regards Gordon www.gordonengland.co.uk www.surfaceengineer.co.uk Photography Obsession | |||
