Titanium carbide (TiC), in addition to other transition metal carbides, has excellent wear-resistant properties in machining of stainless and high speed tool steels.
Down-hole NMR measurements (thousands of meters below the surface) face the challenges of high temperature, high pressure, strictly limited size of instruments and high speed tool movement.
In this work, three high-velocity oxy-fuel (HVOF) sprayed WC Co coatings with different carbide size (0.2, 2, and 6 µm) on high speed tool steel substrates were fabricated and then grinded to produce cutting tools.
TiN films were deposited by ion plating on high speed tool steel substrates, and implanted by carbon ions with fluences up to 5×1017 ions/cm2 and with energies ranging from 50 to 150 keV.
Using the same coating process, two coating architectures were deposited on the high speed tool steel and Si wafer, one starting with an Al N layer designed as the Al N/Cr N/…/Cr N/Al N (architecture A) and the other starting with a Cr N layer designed as the Cr N/Al N/…/Al N/Cr N (architecture C).
It is mainly used to produce specialty steel alloys such as high speed tool steels.
For high speed tool steels, a hardness above HRC 60 can be achieved.
Vanadium high-carbon steel alloys contain 0.15% to 0.25% vanadium and high speed tool steels (HSS) have a vanadium content of 1% to 5%.
Tungsten-containing high-speed tool steel came to public attention when the Bethlehem Steel Company exhibited its products at the Exposition Universelle of 1900 in Paris.
The tribological properties of chlorine-implanted TiN films prepared on high-speed tool steel were investigated.
Tools are made from tungsten carbide, high-speed tool steel, and single crystal diamond.
