Amorphous alloy strips for razor blades - which are based on nickel or iron, are coated with PTFE, and remain ductile after baking

摘要

Razors are mfd. using at least one strip or blade of an amorphous alloy contg. by wt. 60-70% Fe; 2-10% Ni; 20-30% Cr and/or Co and/or Mo; and 2-3% of >=1 metalloid. The strip or blade has at least one cutting edge coated with a fluorinated carbon polymer, followed by heating 8-30 minutes at 330-357 degrees C. The polymer is pref. PTFE, with heating at 343 degrees C. The metalloids are esp. P, B, C, Al, S, Si, Ga, Ge, As, Se, and/or Te, esp. P, B, and/or C; and the alloys specifically contain (1) 5.4% Fe, 51.3% Ni, 10.1% Cr, 22.9% Co, 7.5% Mo, 2.8% B, are coated with polymer and heated at 330-371 degrees C.; or (2) 65.1% Fe, 9.6% Ni, 17.1% Cr, 6.2% Co, 0.13% Si, 1.9% B, are coated with polymer and heated at 330-371 degrees C.
