Sommario/riassunto: | Thousands of patents address new coating types, new developments, new chemical compositions. 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. It is of most val |
