I have a friend who is an Indian-American, very well trained PhD in MSE (material science engineering). I showed him the list of needed products and he said he's very familiar with a lot of them. But doesn't want to go to India because the salary is too low and he doesn't think the government takes R&D seriously enough to make it worth it for him.

Is he a Jew?

He is correct. There ain't no thousand talents program happening here.

Your friend is absolutely right.

Your friend wouldn't have to worry about salary if the Govt pursued this project with the seriousness it deserves.

Infrastructure, testing facilities, machines, top talent, ((( transfer of technology ))), stealing technology, reverse-engineering all face the bottlenecks of mostly money and a little time..

From what I understand we haven't mastered EBPVD although DMRL is working on it . The machines for this is also procured from the west - Germany to be precise. I'm getting conflicting information about it. One source claims we have it or if we don't we can get it while another claims we don't have them & Germany is sitting on our import requirement.

On a different note makes one wonder whether the Russians & the Chinese have them for this treatment is usually done to ensure uniform TBC application for temperatures above ~ 1500°C ?

However the usual YSZ coating a type of TBC which was / is still deployed with the method of application being PS - Plasma Spraying has issues both with the TBC material & mode of application .

One wonders if this is the explanation for the short TTSL of Russian TFs & by extension Chinese TFs since they're mostly derived from Russian TFs including the mfg processes.

Before busybodies jump up & down at the above piece of information on Russian & Chinese TFs , pls let me clarify I'm speculating.

Keep hunting out for nuggets of information. That's how we'd be able to connect the dots.

I've been pushing him really hard to take a professorship at IIT but he's refusing to even apply for the same reasons.

Chinese and Russians are posessing 4th gen engines as well asbadancing on 5th gen. Pretty theyvmust be hav8ng these techniques otherwise they won't be having 4th gen engines.There was nice chart shown in one of the recent IAH by DDR about chinese material and parts development timeline.

EBPVD is there is ARCI hyderabad but due to size constraints (as per tweet) they are only used for blades of helicoptercengine. Not much information on ARCI besides this:

Improvements in gas turbine performance ​

The objectives of this DST-EPSRC project, 'Improvements in gas turbine performance via novel plasma spray coatings offerings protection against ingested species', are to obtain improved understanding of how ingested species can cause degradation of the performance of ceramic coatings in gas turbines and to identify effective measures to counter these effects. Explore the scope for using variants of the conventional plasma spray process, notably Solution Precursor Plasma Spray and the over-spraying of "scavenging" outer layers, in order to counter sintering effects within protective coatings (promoted by ingested species) and hence to improve their thermo-mechanical stability is also the objective of this project. Identify the coating formulations with improved resistance to CMAS/VA-enhanced degradation through the use of rare earth zirconates based ceramic powders as well as solution precursor derived coatings are the targets of this project


Indigenous Development Of Thermal Barrier Coatings On High Pressure Turbine Rotor Blades For Helicopter Applications



Development of protective coatings for compressor blades and vanes using cylindrical cathodic arc PVD technique
The key objective of the project is to develop and demonstrate an indigenous erosive wear resistant coating for helicopter engine compressor blades and vanes. An optimized TiN coating was developed using Cathodic Arc Physical Vapor Deposition (CA-PVD) technique and supplied 510 no.’s of coated blades and vanes for field testing. The coated blades/vanes successfully completed 300 h of flying and RCMA Chandigarh has issued the final clearance for ARCI TiN coatings.
