Ok I tell you one by one my problems. First I am trying to remove the heat treated scales/oxide layer from the internal side of the piston becasue this side doesn't get any machining operation as compared to outer side. Actually when ever I compare internal side of my pistons to any other manufacturer I found that my pistons have stains and the surface is dull. It is not good esthatically. But other's pistons have shining like orignal aluminum or color like that. I don't know exactly what is this. you may ask any question. if still you cann't understand me. Second I have seen various coatings on pistons but I don't know thier exact names but I can guess their names lik Oxidated piston, phosphated pistons, grahite coated pistons and stannate pistons etc. I don't know how can i access to these method. Please do suggest me some solution.

Please let us know what is and what is not acceptable in the finished product. -Paul [/color] info@finishingtalk.com (Southern Metal Finishing) Sat, 23 Sep 2006 15:05:03 +0000 http://www.finishingtalk.com/community/post290.html#p290 http://www.finishingtalk.com/community/post287.html#p287 Hi, I am a new member of this forum, I want to share a problem with all fo you with this hope, someone will show me the right path.
