Can someone tell me why int he world we dont have carbide chain in wide use? It seems to me it would be way better than sharpening evry few tanks a fuel like we do now.

It doesn't hold as sharp of an edge, so it doesn't cut as fast as a properly sharpened chain. But then 8 out of 10 people running saws wouldn't know a sharp chain if it bit them in the fanny, so perhaps it should be used and leave real chain to the pros.
It is also prohibitively expensive for most users.

Brain, I believe carbide could be just as sharp as regular chain. Look at circular saw blades. also It would stay sharp much longer.

Fire departments use carbide chain for cutting through roofs and such. It sucks for cutting wood. It's been a long time since this was discussed here, but there should be some threads on this if you look back far enough. Everyone with any experience using carbide chain said it sucked.
I agree with you there. Its because the carbide chain available is made for cutting roofs, metal, etc. I am talking about a newly designed wood only carbide chain. Most wood working tools have been carbide for years, same with metal machining tools.

Designed to wear out?
You need to hang out with Politicians, Accountants, legal and maketing departments to answer this question
How many loops do you use of non carbide?
If we went carbide what would wear out first? Cutter or chain rivet failure ?

Carbide is very brittle. If you give it angles where it will self feed, you will fracture the edge. In metal machining with carbide, tool clearance is about 5 degrees. It takes a lot of pressure to make it cut though. In a steel chainsaw chain the top cutter clearance angle is around 12 degrees to make it self feeding. I have heard that the carbides take a lot of pressure to make them cut and at ten times the price hardly a bargain. Bet they'd be hard on files.

Diamond file
You would have to go to a diamand dust impregnated file to sharpen a carbide chain?
Had a 9,000 square foot wood shop with 4 table saws which kept the blade sharpening service very busy.
long ago on this site I asked why we don't finish up the sharpening with a very fine diamond file to get a mirror finish.
The conclusion was a steel chrome chain won't hold the edge?
So what material is best to hold an edge on a chain?
How do they get the carbide or chrome on the steel anyway, electrolosis?

What grade of titanium?
The cheap kind 4Al or the armor piercing type?
Purhaps we should look at a depleted uranuim kerf ?
We could replace the kevlar safety pants with a lead jock strap.

the crome on a cutter is electroplated I imagine. Carbide would have to be silver soldered or use some other method of molten metal fastening.

why is carbide chain not used much ? my only answer is maintaince & cost.

I have several thoughts on that:
Carbide does not take as sharp of edge as tool steel.
We would start seeing chain chassis wear out before the cutters.
It would have to be resharpened on a machine with a diamond wheel and very rigid holding of each cutter. That would pretty much rule out the do it yourself sharpener guys.
I suspect there would me many failures of the carbide (breaking off)
I resharpen circular carbide sawblades, so I have had a little experience with it.
It would give Art Martin nightmares.
