However, sometimes coatings is still considered as an ""art"". This book now deals with questions that are essential for a good performance of this ""art"": Is there a given process stability? Is there an inherent process capability for a given specification which cannot be improved? What is the right preventive maintenance strategy? Is there a chance to end up with coating process capabilities in the order of other manufacturing processes? This book is not a pure scientific book.
