Mettech launches NanoFeed 350 second generation suspension delivery system
- Published Date
June 25, 2011. Mettech launches the NanoFeed 350 second generation suspension delivery system.
The Mettech NanoFeed Model 350 Suspension Feeder is designed to deliver nano scale, fine micron or sub micron powders to Axial III Plasma coating equipment. The NanoFeed 350 is the result of customer requests for a cost-effective, more compact suspension plasma spray coating development tool, but is built with the same exacting quality standards incorporated in the NanoFeed 750. Utilizing Mettech’s experience in ultra-fine powders and nano-engineered coatings, all aspects of the suspension delivery, such as flow rate and injection pressure are precisely controlled.
The NanoFeed system has been engineered for use in thermal spray to produce nano structured coatings for emerging nano materials as well as established industrial applications to produce high performance surfaces. It delivers a stable, pulse-free suspension stream, to achieve repeatable, high quality coatings.
Features
• Suspension Powders from 10nm to 10μm
• Mass Flow Control of Suspension Feed
• Graphical Flow Rate and Operator Display
• Stand Alone Suspension Feed Unit, or Integrated into Plasma Torch Control Unit
• In Tank Agitation

ABSTRACT
Thermal barrier coatings (TBCs) have been employed for many years to protect the metallic components of the hot sections of aerospace and land-based gas turbines against the high temperature environment. These coatings are generally made by either air plasma spraying (APS) or electron beam physical vapour deposition (EB-PVD). In general, EB-PVD TBCs have superior durability due to the columnar structure, but they are very expensive compared to APS TBCs. EB-PVD TBCs are used primarily in the most severe applications such as turbine blades and vanes in aircraft engines. This paper presents an economical process to make durable TBCs, called Axial Suspension Plasma Spray (ASPS). This technology combines Mettech’s axial injection plasma process and automatic suspension feed system. The resulting TBCs exhibit a columnar structure with substantially equiaxed grains, instead of the typical lamellar structure with flattened particles for APS TBCs. Such structures allow the TBC to compensate for thermal expansion differences between it and the base material, resulting in excellent durability. The ASPS process presents a significant potential to replace EB-PVD for aircraft turbine parts and offers an economical method to deposit durable columnar TBCs.
