Pulsed laser deposition of fluorocarbon polymers on razor blade edges.

摘要

Provides a method of depositing a thin and uniform fluorocarbon polymer coating on a multi-sided substrate to reduce friction and reduce cutting force, particularly a method of depositing a thin and substantially uniform film on the edge of a razor blade To do. The disclosed method includes a laser at a wavelength of about 200 to about 1000 nm for a pulse length of 100 femtoseconds to 10 nanoseconds, an intensity of 1 microjoule to 1 millijoule per pulse length, and a repetition rate of 100 kHz to 1 GHz. Including pulsed laser deposition. [Selection] Figure 1
