is this knife titanium coated?
Not coated, solid (as far as I can tell). What I can tell you without any question whatsoever, is that I've dived this knife for at least 6 years now (I think longer)without the first speck of rust. It takes a good lasting edge too.
I do not believe that the blade is titanium coated in any way. The blade is actually made of titanium.
Titanium is a chemical element with the symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density and high strength. It is highly resistant to corrosion in sea water, aqua regia and chlorine.
Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and named by Martin Heinrich Klaproth for the Titans of Greek mythology. The element occurs within a number of mineral deposits, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere, and it is found in almost all living things, rocks, water bodies, and soils. The metal is extracted from its principal mineral ores via the Kroll process or the Hunter process. Its most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and titanium trichloride (TiCl3), which is used as a catalyst in the production of polypropylene.
Titanium can be alloyed with iron, aluminium, vanadium, molybdenum, among other elements, to produce strong lightweight alloys for aerospace (jet engines, missiles, and spacecraft), military, industrial process (chemicals and petro-chemicals, desalination plants, pulp, and paper), automotive, agri-food, medical prostheses, orthopedic implants, dental and endodontic instruments and files, dental implants, sporting goods, jewelry, mobile phones, and other applications.
The two most useful properties of the metal are corrosion resistance and the highest strength-to-weight ratio of any metal. In its unalloyed condition, titanium is as strong as some steels, but 45% lighter.
It's a great dive knife. I've had mine for over four years. And after heavy use, it still looks brand new. I will definitely buy another one when ever that time comes. It's going to be a while though, these knives just lasts for a long, long time.
Not a coating, solid titanium.
it seems solid to me. It is not that hard, and must be re-sharpened often (regular file fine). It just does not rust or tarnish, even with no rinsing. Great knife!
