METHOD OF PRODUCING THIN-FILM COAT ON RAZOR BLADE Russian patent published in 2012 - IPC B26B21/60 C23C14/34 C23C14/35 

FIELD: process engineering.

SUBSTANCE: invention relates to method of razor blade formation. Proposed method comprises the following stages: fabricating substrate, producing wedge-like sharp edge on substrate with internal angle smaller than 30° and radius of rounding smaller than 1000 Å, placing said substrate into vacuum chamber, fitting first solid target into said chamber, feeding gas therein to ionise and generate ion flow from said first solid target by applying pulses of negative voltage to first solid target. This makes ions make thin-film coat of aforesaid sharp edges.

EFFECT: higher quality and durability.
