| 摘要 |
The invention relates to a thermal spraying method and a device for coating the inner surface (24) of a cylinder (10) of an internal combustion engine or piston engine, the method comprising the following steps: - applying a thermal spray layer (24) to the inner surface (26) of the cylinder (10), and - optically detecting the surroundings (15) of the spray jet (13), namely a space outside the spray jet (13), by means of an optical sensor device (12). If the optical sensor device (12) detects particles of the spray material (14) supplied to the spray torch (11) in the monitored area (15) outside the spray jet (13), the coating process is assumed to be defective. |
