How to increase friction resistance on hardener stainless steel
(OP)
Hi,
I have a basic question. I am not a metal specialist.
How to increase friction resistance on hardener stainless steel blade?
Smooth Blade (V profile blade) is shearing copper wire in constant cycle production.
TiNi coat will be good?
Thank you for all answers.

Any reason not to switch to a tool steel? You might have lower corrosion resistance (or maybe not) and with the correct grade you could get longer life.

How to increase friction/wear resistance on hardener tool steel shear blade? Coat TiNi or smth else?
Thank you for support.
RE: How to increase friction resistance on hardener stainless steel
I'd like to ask you for support to chose best process.
Action:
Cut-off (hardener tool steel,tested 64HRC) blades cutting copper wire OD=2mm during serial production. V profile blades shearing this wire and after 15k cycles new blade edge is dulled/blunted.
Which process will be the best for increase of wear resistance?and why.
I think about: 1st - TiCN coat t=3mikron or
2nd - ion nitriding or 3rd - burnishing.
Thanks a lot.

RE: How to increase friction resistance on hardener stainless steel
I would like to improve the friction resistance by some metallury process and I am not sure which.
Which process in this case should be in the scope?
RE: How to increase friction resistance on hardener stainless steel
Seems that the expense of retreating and specially fabricating the stainless steel blade gretaly exceeds the much lower cost of simply getting a hardened tool steel blade, getting more cycles because of the heardness (20,000 to 25,000 maybe) and still not getting corrosion problems over the short extension to life.
Then get a new, cheaper blade. Repeat.

RE: How to increase friction resistance on hardener stainless steel
First I will try with coat TiCNi coat at 400 deg C increase to above 95 HRC increasing wear resistance.
What about ion nitriding or burnishing ? Do you think can help and why?
thank you.
