So I send to all of the group subject Sun, 01 Nov 2009 23:08:27 GMT Shoaib mirza http://tech.groups.yahoo.com/group/PVD_coatings/message/5650 http://tech.groups.yahoo.com/group/PVD_coatings/message/5650 Dear Minoj, Do you use pre-cleaning of your job before coating. There are many causes of poor color and adhesion. Mention the material of work piece and also Sun, 01 Nov 2009 23:07:58 GMT sodky abolila http://tech.groups.yahoo.com/group/PVD_coatings/message/5649 http://tech.groups.yahoo.com/group/PVD_coatings/message/5649 Dear Colleges Is anybody knows suppliers for: 1- A high intensity UV light source with two different wavelengths for microscopic glass slides illumination. 2- Sun, 01 Nov 2009 23:07:51 GMT Satish D http://tech.groups.yahoo.com/group/PVD_coatings/message/5648 http://tech.groups.yahoo.com/group/PVD_coatings/message/5648 Manoj, Please check for vacuum leaks using a good leak detector. Moisture can kill the coating. Contact my friend Dr. Sanjay Patil at H. Fullinger in Pune.

We can help you build such a system which can be used for both cathodic arc and sputtering. Regards H.R. Prabhakara ...

The temperature should be high during sputtering. This could perhaps be achieved by adjusting Sun, 01 Nov 2009 23:05:36 GMT gigawatt6@... http://tech.groups.yahoo.com/group/PVD_coatings/message/5643 http://tech.groups.yahoo.com/group/PVD_coatings/message/5643 What is the vacuum level before the first level and the same for the second level? Do you have a RGA to scan the system, pre and post?
