Mettech Launches NanoFeed 350 Second Generation Suspension Delivery System

25-Jun-2011

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

Mettech to Present at the 5th International Workshop on Suspension and Solution Thermal Spraying October 3-5, 2011

25-Jun-2011

Mettech is pleased to announce that we will be presenting at the 5th International Workshop on Suspension and Solution Thermal Spraying, October 3-5, 2011 in Tours, France.

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.

Mettech Signs Development Agreement with Chinese Academy of Sciences

19-May-2007

Northwest Mettech Corp. announced today that the Company has signed a Technical Cooperation Protocol with the Institute of Metals Research (IMR) of the Chinese Academy of Sciences (CAS). IMR is the country's national center for high performance nanomaterials, advanced coatings and composites. Under the terms of the Agreement, Mettech and IMR have targeted a group of industrial research projects aimed at delivering Mettech's nanopowder coating technology to Chinese aerospace, steel and power generation industries.

The signing ceremony, held in Shenyang, China, was attended by representatives of Mettech and the National Research Council Canada Industrial Research Assistance Program (NRC-IRAP). Chinese representatives included representatives from IMI and the local state government.

"We are very honored to be chosen as a development partner with the Chinese Academy of Sciences and are looking forward to working closely with them and their industrial clients to provide the next generation of high-performance nano-engineered coatings. We are very grateful for IRAP's help in facilitating this cooperation through their direct involvement in China", said Gary Albach, CEO for Mettech, during the ceremony in Shenyang.
