What is TiN coating?
Titanium Nitride (TiN) coating is wear resistant, inert and reduces friction. TiN coatings are easily peeled off tool steels. This makes TiN an ideal coating for applications that use expensive tooling, such as injection molding and forming.
Advantages of TiN coating
TiN is applied as a thin coating to harden and protect cutting and sliding surfaces, for decorative purposes (due to its golden appearance), and as a non-toxic exterior for medical implants. Apply coatings less than 5 microns (0.00020 inches) in most applications
TiN is a hard ceramic coating, commonly used on steel drills and other machine tools, which has several advantages, mainly longer edge retention and reduced friction. In other words, TiN-coated bits should last longer than uncoated bits, and you can usually push them faster too.
TiN Coating Frequently Asked Questions
Is TiN coating good for aluminum?
Can I use TiN in Aluminum? limit. Chemically, titanium has a special affinity for aluminum. During drilling, under the influence of pressure and heat, chemical and physical diffusion processes are triggered, especially in the cutting edges and chip flutes.
Is tin coating safe for cooking?
Tin layer as a safe substance between metal and food Tin helps utensils made of brass and copper increase their electrical conductivity, thereby reducing fuel costs. It also preserves the flavor of your food by re-tinning it periodically.
How does tin coating work?
Titanium Nitride is a bright gold-colored ceramic coating that is applied to metal surfaces by a physical vapor deposition (PVD) process. Wallwork Cambridge uses an electron beam evaporation process under vacuum to produce TiN coatings at workpiece temperatures below 500oC. ...
Is tin harmful to the human body?
Because inorganic tin compounds typically enter and leave your body quickly after you breathe them in or eat them, they usually do not cause harmful effects. However, humans in studies who swallowed large amounts of inorganic tin developed stomach pains, anemia, and liver and kidney problems.
Can you sharpen a TiN coated drill bit?
You can use the Drill Doctor to sharpen almost any drill bit you could possibly need, including HSS, TiN coated, cobalt and even masonry bits.
What is titanium nitride used for?
Titanium nitride is a refractory compound with high microhardness and chemical and thermal stability. TiN has a variety of applications: as a component of special refractories and cermets, as a crucible material for oxygen-deficient casting of metals, and as a precursor for wear-resistant and decorative "gold-like" coatings.
Which coating is suitable for cutting aluminum?
Diamond and DLC coatings make the surface very smooth and chemically inert. These coatings have been found to significantly increase tool life when cutting aluminum. Diamond coatings have been found to be the better performing coatings, but there is a considerable cost to this type of coating.
