I am not an expert in metals or finishing but merely describing what I and several others have experienced. Your comment would suggest to me that instead of the PVD process itself being inefficient, the low cost of modern golf equipment and the massive volumes may well force some of the manufacturers that apply the PVD to cut corners. From my experience certain types of sand under the club appear to act as "sand paper" and scratch off the PVD quite easily. Thanks for taking the time to comment.

]]> Comment on PVD Coating on Golf Clubs – Good or Bad? by Michael http://www.golfingtrends.com/pvd-coating-on-golf-clubs/#comment-90 Michael Sun, 25 Mar 2012 11:46:20 +0000 http://www.golfingtrends.com/?p=133#comment-90 I have just completed a study on new applications of PVD. To be honest, I find it inconceivable that this coating should just come off. The process deposits a coating that is bonded to the substrate and its thickness is measured in microns. Its widest and oldest application is for coating milling tools - like drill bits for industrial use, where you see steel parts being drilled, milled, turned, etc using such coated tools. The coating does eventually come off there, but imagine that such a tool gets through about 200 holes made in hardest steels at high speed before it needs recoating. Various heavy machine wear parts, auto parts, milary vehicle parts and so on are coated with this technology. All these parts come under enormous stresses, incomparable to what golf clubs get. PVD is also used on joint implants and studies have proven that this ensures no flaking of metal, which has happened with uncoated implants made of titanium, leading to a major recall in the US. For this reason more and more implants are being PVD coated. So, again, it is hard to believe that a genuine golf club with genuine PVD coating would suffer the kind of damage you describe here.
