I ordered a cryo in the matte gray titanium coating. How does this Chinese coating hold up? How would it compare to maybe richter or northeastern coating Titanium Carbon Nitride?

Any feedback would be helpful
 
I don't know much about the coating itself, but I decided to really try out my Cryo 2 and I must say I am really impressed. The coating has held up very well scratches are a lot less noticeable then the scratches on the black DLC coating. So use it you won't be disappointed in the coating at all
 
I must agree with coli. I don't know the specifics about the coating, but it holds up better than expected. It will show scratches after you've put some work in, but they don't show all that much. I'm sure you will be pleased with your purchase. I love my Cryo.
 
Great! That's what I needed to hear. Thanks guys. I was just wondering if anyone has sent their knives out for coating. I think titanium nitride is cool and not my people have a gold folder lol.
 
The cryo came in today and I love it! However I managed to strip one of the screws for the clip when relocating it. But I put loctitep on it and I shouldn't go anywhere
 
Awesome to hear, man! I seriously can't say enough good things about this knife...it's one of my favorites.
 
HRC is hardness on the Rockwell C scale. TDLC (Tungsten diamond like Carbon) is actually Tungsten Carbide with an HRC around 72.
TiiN (Titanium Nitride) is the dark gold coating you sometimes see on drill bits. It has a hardness around 82. ZrN (Zirconium Nitride) is a champagne gold coating with a hardness of around 85.
TiCN (Titanium Carbonitride) has a slight purple cast to it and Rockwells around 88. TiAlN (Titanium Aluminum Nitride) is a charcoal colored coating and has a hardness of around 92.
They also have CBN (cubic Boron Nitride) which I have not seen hardness figures for. None of the above coatings are too shabby. They are all used to extend the life of cutting tools in some instances being applied in multiple alternate layers because some have more resistance to heat, shock, abrasion, etc. than others. I have some spotting drills with 10 layers of multiple coatings. I have a fractional drill set coated with ZrN and a wire gauge # drill set coated with TiAlN.
 
This is all very interesting. I was reading about richter and northeastern services but this cleared things up a bit. But shouldn't I be worried about application temp. Wouldn't high temps mess up tempering of 8cr13mov or any other medium carbon stainless?
 
My experience with TiNi has been very favorable. I had it on a tenacious, and also a beater SanRenMu 710. It held up wonderfully and wire very slowly, ultimately becoming reminiscent of slightly faded jeans. Highly recommended, especially compared to Teflon coatings. Even DLC has a downside in that it has a bit of a texture that drags a little when cutting, whereas the Ti coatings are smooth.
 
I called Titanium Nitride TiiN. It's really TiN. TiNi is Titanium Nickel. Physical Vapor Depositon involves heating the material to be deposited hot enough to vaporize it, but the target is not subjected to excessive heat.
 
Is it true titanium coating, meaning it can be heat color anodized?
 
Not at all. The coating is a Titanium compound (salt). Iron is a metal. Iron oxide is a compound (rust). Titanium is a metal. Titanium Nitride is a compound (borderline ceramic). Copper is a metal. Copper sulphate is a compound (blue crystal). ETC.
