Some cermets

Aluminium and zinc are what is called "amphoteric" metals....meaning they do react with both acids and alaklies. Thus it makes little difference...

It does not work that way. You can not separate mixtures of volatile components effectively by just heating the mixture in the hopes of the lower boiling...

These tricks usually tend to yield a very minuscule effect since the cooling rate during the quench is already so steep that the surface of the part is...

I probably confused people with the original title of the post.....the inserts are not of "Cermet" brand origin, but I refferred to them as...

Thanks for the reference....I've also stumbled on these resources while I tried to figure out the generic composition for these alloys. Problem is that...

General consensus states that a burn or deflagration shall be redefined as detonation when the shockwave/reaction front propagates at a supersonic speed...

Yes they are, but tightening from one of the three points drags the rest of the system behind. By going through all of the three, one helps to relieve...

I have little to none samples with known verified composition available as far as alloyed steels go Mild construction steel is pretty much the least...

[markx]

Sure as heck the mild steel container that I performed the process in has carburized....almost straight through to the outside surface (that was a 2+...

[markx]

For sure, but I have no confirmation at which chromium content the diffusion barrier effect treshold might lie....could be at 0,1% but might be at 5%...

[markx]

Depends on what kind of energetic materials we are talking about. For high velocity HE-s I can not really fathom a known container material that shall...

The BOK-60 variety is actually very tough even in interrupted cut modes. When I machined the HSS threading die, it bashed against the flutes like nothing...

I guess different alloys are used for producing the bolts, hence they may also show...

I'm doing this solely for fun and personal learning curve If I needed a specific part with guaranteed properties and within a tight schedule then I...

Arrrgh....that was a bust!! The Great Architect was not supportive of my cause today. First of all the lid on the pack got stuck and by the time I managed...

[markx]

Well, she is back together in one piece. But I have the sinking feeling that my colleague is trying to break a tap into the lid this time

[markx]

She is heating up to temperature. The plug is contained in the vessel made from rectangular tube. I added a piece of wire to the tang so I can lift the...

[markx]

True....they do have a rather special edge geometry. It's for reinforcement purposes as the ceramic material tends to be rather brittle. But they work...

Picked up some old cermet inserts from bygone soviet times. Quite interesting and capable gadgets: TH-20 are a type of tungsten free hard alloy based...

It's for a remote controlled tracked vechicle. Not my project.....a colleague of mine is developing "the tank" as we call it ...
