Titanium Nitride Coated Cast Iron

[Trevanion]

I thought this was interesting, Axminster are selling Harvey band saws now that have a TiN coating on the bare cast iron surfaces:

As it turns out Harvey also make a table saw with a TiN coated top:

It will be interesting to see the longevity of such a coating on cast iron, or whether it's just a gimmick and it'll look very patchy after a couple of years of hard use. The low friction and no corrosion pros are quite appealing, and it does have a certain wow-factor that some may like...

I wonder how much that adds to the cost? Cast Iron is already pretty good anyway. It’s Nitride by the way, not Nitrate.

The Harvey table saw with the coating has had a lot of good reviews

Having tried to machine the cast iron on an Axminster mortiser once only to have it crumble I can guess why they want to coat it.

Can't be as bad as the Charnwood stuff, I sold a bandsaw I had in storage for a long time the other day and I noticed there was an odd-shaped indent on the edge of the table and after a bit of probing with a stanley knife blade, I realised there was a huge chunk of car body filler under the paint replacing a 2" section of cast iron.

Why not do the job properly and coat the tables with unicorn tears?

Did you guys ever have the granite tablesaw tops like we had a few years ago? Another flash in the pan gimmick didn't last.

Those were the "Steel City" machines weren't they? I think they also did a bandsaw that had granite wheels, which seems a bit daft too.

Granite table there too. I don't think wheels--I can't imagine that they would survive the stress very long.

A quick google brought this article up:

Obviously, they didn't do them for long as I can't find much else about them except for a few forum posts. I can't imagine them being the cleverest idea, a small fracture would turn into a large one very quickly!
