EU Hot on Novel High-Temp Coating

A multinational effort is well underway to develop an unconventional coating that would combine a thermal barrier, oxidation and corrosion protection, lotus effect, and fire protection in one product.

The European Union's ambitious, multiyear PARTICOAT project is based on tailoring nano- and micro-scale aluminum particles (powders) in the coating product.

The European Union's multiyear, multinational PARTICOAT project aims to develop a novel, multifunctional nano-based coating for high temperatures and extreme environments.

The goal is to develop a multipurpose coating system for extreme environments at high temperatures for a wide variety of application areas, including:

  • Gas and steam turbines in electric power generation and jet engines;
  • Abradable coatings;
  • Combustion chambers and boilers;
  • Steam generators and superheaters;
  • Waste incineration;
  • Electrical insulation in arc melting furnaces;
  • Fire protection of composite construction materials; and
  • Reformers and reactors in the chemical and petrochem industries.

Results thus far demonstrate that the concept is viable, according to PARTICOAT. The consortium has 14 national and multinational academic, corporate and research partners in Germany, Greece, Czechoslovakia, Italy, Russia, France and other countries.

The Big Idea...

The project envisions a thermal barrier coating in a combined bondcoat/topcoat system that is formed in one single thermal treatment step.

Coatings produced so far by the PARTICOAT project include a metallic green binder (left) that tolerates 600°C and a ceramic binder (right) that withstands 900°C. The consortium consists of 14 research, academic and industry partners. T

The concept involves a protective coating "consisting in its initial state of nano- and/or micro-scaled metal particles with a defined size" that can be applied by spraying, brushing, dipping or sol-gel, according to the project's website.

...And its Nano Steps

The explanation, from the site:

"During the heat treatment, the binder is expelled and bonding to the substrate surface achieved. Using the adequate parameters, the metallic particles sinter and oxidize completely resulting in hollow oxide spheres that form a quasi-foam structure.

"Simultaneously, a diffusion layer is formed below the coating serving with the appropriate coating element as a corrosion protection layer and as a bond coat for the top layer."

PARTICOAT partners

PARTICOAT's partners include a variety of national and international university, research, and small- and medium-size (SME) companies across Europe.

Graded coating structures are possible by varying the source metal and/or the particle size, the project reports.

"The structure and the final properties of the coating system shall be adjusted by parameters like selection of source metal/alloy, particle size, substrate, binder and a defined heat treatment, which can consist of one or more steps."

A technical presentation details the project.

The ultimate goal is a coating that increases durability of high-temperature components, an increase in safety, and a "step change" in the understanding of materials degradation mechanisms in extreme environments.

Sounds is good... Well potential!!!!i would like to know the coating type? One component or two? At how much thicknesses can be applied? Also curing time ? Can be applied on ambient temperature before heated ?
