SILICON-DOPED AMORPHOUS CARBON COATING FOR PAINT BELL ATOMIZERS

摘要

The present invention relates to a wear-resistant coated bell sprayer (32) and a method of manufacturing the same. The coating applied to the outer surface of the bell cup 36 of the bell sprayer 32 is preferably a silicon-doped amorphous carbon coating. The siliconized amorphous carbon coating limits the effect of the abrasive material on the wearable surface of the bell cup 36, including the upper funnel edge 46, which may adversely affect the performance of the uncoated bell sprayer device, Thereby significantly increasing the life of the bell cup 36 of the sprayer painting system 10.
