Claims
- 1. A method for the preparation of a microtome blade coated with a layer of diamond which comprises the steps of:
- (a) subjecting a base blade to a treatment of plasma-induced chemical vapor deposition of diamond by exposing the same to an atmosphere of plasma generated in a gaseous mixture composed of a hydrocarbon compound and hydrogen; and
- (b) subjecting the base blade thus coated with a layer of diamond to a heat treatment at a temperature in the range from 700 to 1300.degree. C. for a length of time in the range from 0.5 to 1.5 hours in an inert atmosphere.
- 2. The method for the preparation of a microtome blade coated with a layer of diamond as claimed in claim 1 wherein the gaseous mixture is composed of a hydrocarbon compound and hydrogen in a ratio from 0.2:99.8 to 10:90 by volume.
- 3. The method for the preparation of a microtome blade coated with a layer of diamond as claimed in claim 1 wherein the hydrocarbon compound is selected from the group consisting of methane, ethane, propane and ethylene
- 4. The method for the preparation of a microtome blade coated with a layer of diamond as claimed in claim wherein the gaseous mixture of the hydrocarbon compound and hydrogen has a pressure in the range from 0.0027 to 2.7 kPa.
