Solution Overview
Problem
Existing powder production methods often result in irregularly shaped particles, making it difficult to achieve consistent sizes and industrial-scale production, especially for metal powders, and existing coating systems do not allow for simultaneous synthesis, separation, and coating processes.
Innovation Solution
A powder coating system that uses plasma atomization or arc plasma methods to convert solid, liquid, or gaseous materials into powder form, with a control unit to manage the process, allowing for simultaneous synthesis, separation, and coating, using a vacuum system to collect powders of predetermined sizes and a movable table for precise coating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mechanical powdering methods are used to break down particles, then powder production is achieved, but the particles have irregular morphology and inconsistent sizes
Solution Approach 1:
The invention uses plasma atomization where feed material is melted by plasma and then atomized into spherical particles through phase transition from solid to liquid to solid, achieving consistent spherical morphology that mechanical breaking cannot produce
Solution Approach 2:
The invention replaces mechanical impact-based powdering methods with plasma-based thermal processing, where plasma provides controlled heating and atomization to produce uniform spherical particles instead of irregular fragmented particles
2Manufacturing precision
If plasma atomization method is used to obtain spherical powder, then particle morphology and size consistency are improved, but the system complexity increases due to multiple subsystems required
Solution Approach 1:
The invention merges powder synthesis, separation, and coating operations into a single integrated plasma atomization system, where all processes occur within the same vacuum chamber, reducing overall system complexity despite the advanced plasma processing requirements
Solution Approach 2:
The plasma processing chamber serves multiple functions: it acts as both the atomization reactor for powder synthesis and the coating chamber for applying powder to substrates, eliminating the need for separate processing equipment
3Productivity
If separate processes are used for powder synthesis and coating, then each process can be optimized independently, but time consumption increases due to sequential processing
Solution Approach 1:
The invention combines powder synthesis and coating operations in the same vacuum chamber, allowing continuous processing where powder is synthesized and immediately coated without breaking vacuum, significantly reducing total processing time while maintaining quality through controlled plasma parameters

AI summary
A power coating system for a material in liquid, solid and/or gaseous form used in engineering applications. At least one feeding unit enables the material to be transmitted at a feed rate predetermined by the user. At least one plasma torch located in connection with the feeding unit enables the form of the material to be converted by the atomization method. A powder in an amount predetermined by the user is formed by conversion of the material by the plasma torch. A plurality of reservoirs allow the powder to be separated and collected in sizes predetermined by the user. At least one transmission line allows the powders to be conveyed to the reservoir. A vacuum unit allows the powders to be conveyed by vacuum on the transmission line where at least one part is pre-positioned by the user into the reservoir for applying the coating process.
