The titanium nitride experiment
Response To:
photomicrographs *PIC* ()

TiN is used on all sorts of cutting tools to lessen dulling. Would it work on a plane blade to prolong edge life? Plain old maple is surprisingly abrasive. In only 50' it wore off this coating to the distance shown in the picture.

When I was investigating something or another I was searching for the coefficient of friction of wood on steel. The value is surprisingly high. It is high because it was found that wood will chemically bond to steel (probably the lignin) with some weak but significant bonds. The objective of these papers was friction, but friction and wear are close cousins.
