AI Technical Summary

Technical Problem

Existing plasma spraying technology for ceramic coatings suffers from inaccurate control of the workpiece angle and driving speed during localized spraying, resulting in uneven ceramic coatings and low deposition rates. This makes it particularly difficult to achieve uniform deposition on workpieces with complex geometries.

Method used

The system employs a circular conveyor belt and a plasma spraying box, combined with a drive base, adjustable legs, and a control system. The workpiece is rotated by a servo motor, and the height and angle of the workpiece are controlled by multiple adjustable legs. The spraying speed and posture are matched in real time, and online thickness monitoring is used to achieve coating uniformity and high deposition rate.

Benefits of technology

It achieves uniform deposition of ceramic coatings on complex workpieces, avoids local over-thickness or missed spraying, improves deposition rate and spraying efficiency, and ensures uniform coating thickness distribution and clear edges.
