Analysis of the Tribological Behaviour of Stainless and Ball Bearing Steels Sliding in the Presence of Sulphur Extreme-Pressure Additives
… (clamped) balls. The tribological behaviour of stainless and ball bearing steel were studied under extreme pressure and/or anti-wear lubrication conditions in the presence of sulphur and sulphur containing additives, in order to compare the wear behaviour of the AISI 420 stainless steel with the …

Determination of Wall Thickness and Height when Cutting Various Materials with Wire Electric Discharge Machining Processes
… the test; Aluminum 6061 T6, Yellow Brass SS360, 420 Stainless Steel, D2 unheat-treated tool steel 25-30 RC, and D2 heat-treated tool steel 60-65 RC. The small parts were cut to a 6mm (0.2362 inch) height with six different wall thicknesses: 0.30mm (0.0118 inch), 0.25mm (0.0098 inch), 0.20mm …

Rehardenable materials system with diffusion barrier for three-dimensional printing
… resistance for 3DP metal tooling consists of 420 stainless steel powder and bronze infiltrant. However, it only has an overall hardness of 25 HRC because the bronze infiltrant is soft and not hardenable. A hardenable 3DP metal system is desirable. The main goals of this thesis research are: 1) …
