Description du projet/ Project Description
This project proposes to develop a combination of a process and an anti-erosion coating which allows one to repair coated components of aircraft’s engines. The coatings should be removed efficiently and in an environmentally friendly way; the impact on the base material and on the performance of the part should be minimized, and the part should be suitable for being re-coated.

The objectives are:
A: To develop a stripping method of anti-erosion protective coatings. The method should exhibit minimum effect on the component’s base material (profile, mechanical properties). Two methods are considered: a) wet chemical removal; b) dry plasma-based removal.
B: To develop and optimize an erosion-resistant coating, fabricated by Cathodic Arc Physical Vapor Deposition (CA-PVD), that can be easily stripped in order to be repaired.

The stripping methods and conditions have to respect the requirements of minimum impact on the environment (green, environmentally friendly) as well as low cost; considerations should include decontamination of the products
used for stripping, low rejection rate of the device etc.

The scope of the project is highly relevant to the nanotechnology-related initiatives in Quebec.
Objectifs/ Objectives
Objective A: To develop a stripping method of existing ERCs via (a) dry etching based on plasma and laser technologies, and (b) wet chemical etching. 

Objective B: To investigate the effect of the etching process on the surface and interface properties of the substrate and on the performance of the subsequently deposited ERCs using physical vapor deposition (PVD).

Objective C: To develop and optimize a new ERC that would, in combination with the specific etching (removal) process, represent an industrially viable solution for reparable compressor blades.
