As some may be aware I'm studying for an HNC manufacturing engineering and have just started the Materials Unit.

As one part of an assignment I have to name lots of components used in the manufacture of modern automobiles. I also have to state the exact material, I can't just say "steel" or "aluminium" i need to also state the material properties and why it is used.

The metallic ones have been a doddle but I'm struggling with ceramics. I need to discuss 4 ceramic materials. I have 3 but I'm stuck on a 4th!

I have so far.....

Brake discs - silicon carbide reinforced with carbon fibre
Engine valves - Yttria stabilised Zirconia
Spark plugs - aluminium oxide (alumina) ceramic

I'm struggling like hell to find a 4th. Ive now spent days on the internet in the evenings and am drawing a blank. Does anyone have any kind of idea or is there by some miracle a Materials Engineer reading this that could point me in the right direction?

Im suffering a bit of 'can't see the woods for the trees' or some such quote and could do with a nudge in a different direction but can't find it.

It would be very much appreciated thanks!

Have you expanded your search to ceramics used in the manufacturing process, rather than just the content in the end product? For example ceramic cores used for casting alloys.

If that's not allowed, then there are a few ceramics in lithium batteries - can you go hybrid? :)

Any clues here ?

I haven't. That sounds like a bloody good idea though. I thought I'd cracked it with catalytic converters but after digging it turns out they use the same stuff for that as they do valves.

I need to name the exact material and also find out the material properties such as hardness (brinnel, vickers etc.) Young modulus, tensile strength, ductility which is where I'm really struggling with it.

I haven't even started on the 4 Polymer ones I need to do yet.

I've already written near on 3000 words and 15 pages and I've only done 9 of 15 materials. Still have another 6 to go and then another 4 questions/tasks.

It's a monster assignment.

Catalytic converter a big one its called cordierite

Oooh. Looking at cordierite it seems they used to use it in DPF's before silicon carbide. Just need to find some tech specs on it.

Cheers!

I already had a look at that. I thought a DPF would be a good shout but they use silicon carbide. I already have that material for brake discs so need another one.

They do make ceramic cats but I've used catalysts already for Platinum in my metals section.

I thought I'd breeze this task but it's a lot trickier than I thought.

You can get tungsten carbide discs... use those and go silicon carbide for the DPF. Tungsten is awesome so good to get it in there somewhere :)

A lot of after-market paint protectors are described as liquid ceramic.Not sure if manufacturers use it.Good luck with your project.

Easy ... switch it off and then back on again
