Thermal Spraying for Power Generation Components covers the capabilities and limitations of thermal spraying.
Features:
- Details deposition efficiency (waste of powder) and the importance of maintenance and spare parts for quick change over of worn equipment
- Explains offline programming and real equipment in an optimum mix to end up with stable processes in production after shortest development time and in the end to achieve the final target in production: process stability at minimum total cost
