Sintering

How does it work then?

I've bought sintered pads for years and not really thought about it. But
now I've augmented my small collection of titanium man bling with a
little tungsten (with carbonfibre).

Reading a little about the tungsten, it seems it is sintered from dust
(!) rather than being cast. From what I've spotted on my brief trip
aroung the interweb, it seems that sintering involves heating stuff up
until it gets sticky then squidging it together, rather than melting it
and popping it in a mould.

That about right or am I way off the mark?

 

Yes that's about correct. You can get solid state sintering and liquid
phase sintering but all involve getting stuff hot. This permits solid
state diffision at the contact points so the particles eventually stick
together. Liquid phase is generally faster and involves local melting of
a small volume fraction of the material. Anything involving tungsten will
probably be solid state.

 

Indeed. Useful where you don't want something really nasty in a molten
state. Like plutonium! (solid state) sintered into fuel pellets. And
if you look at HH pads they are same (not Pu obviously)

Now I'm fantasising about a system where hammering on the front anchors
initiates a criticality ;o)

pah

I nearly achieved that this morning.

It appears friction is less in cool, humid conditions...
