Among all lubricious substances that are in use industry wide, the most used dry and solid option seems to be Tungsten Disulfide (WS2. The rarity of the dry lubricity offered by WS2 is pretty much visible when you compare it to graphite and similar other substances.
The use of WS2 dry lube is quite visible in industries that are dealing in high-pressure temperature and applications. Under usual conditions, WS2 offers substantial resistance towards rising temperature varying between -270º C and 650º C. The coated film offers a load-bearing capacity of 300,000 psi, which is considered quite high as per the industry standards.
Compared to MoS2 (Molybdenum Disulfide), the use of Tungsten Disulfide (WS2) is preferred. You must check the comparison of WS2 and MoS2. The applications do not follow any limitations owing to the minimal Coefficients of Friction yielded by the powder (that is considered static at 0.07 and dynamic at 0.03; you can make an attempt with every conceived idea.
The Best Options of Using the WS2 Dry Lube:
1) Getting the lubes and WS2 powder blended:
Depending on the industrial need, you can blend the powder with oil or grease between 15wt% and 1wt%. The combination will thus acquire an upgraded lubricity and even offer some properties based on Extreme Pressure and High Temperature while blending. While utilizing it, the presence of WS2 dry lube in the mix protects the mating or moving parts, thus extending the capacity to bear more burdens.
2) Developing a coating with WS2 powder on the lubricious substrate:
When you shower the substrate with dry (and cool) pneumatic air at 120 psi it gets covered. There is no need to use the fasteners and you can easily splash at typical room temperature. The thickness of the film thus covered will be worth 0.5 micron. Blending the powder with Isopropyl liquor is quite possible using an elective application technique; you may polish the glue over the substrate.
The coating applications prove to be very effective for a wide range of auto body parts varying from automated components and racing car engines. A number of cutting tools, knives, marine components and slitters are amongst the parts using dry lube.
