A complex of lanthanum and N-salicylidene derivative of malonic, dihydrazide (Schiff base) was synthesized, and its tribological properties as additive in lithium grease were evaluated using a block-on-ring wear tester with a SAE52100 steel ring against an Al 2024 block. The protective film formed on the rubbed surface of aluminum was investigated by SEM, XPS and AES. Friction and wear tests reveal...
Glass-ceramic and glass substrates are beginning to be used in the construction of magnetic thin-film rigid disks for their rigidity, shock (dent) resistance, and smoothness over commonly used Ni P coated aluminum-magnesium substrates. Coefficients of static friction (stiction) and kinetic friction in clean ambient (class 100) and durability in various environments were measured for disks constructed...
Chemically strengthened glass substrates have recently been used in the construction of magnetic thin-film rigid disks for their rigidity, shock resistance, and smoothness over commonly used Ni P coated aluminum substrates. The effects of disk roughness, lubricant film thickness and viscosity on coefficients of static and kinetic friction and on disk durability were investigated for disks constructed...
