Abstract
The disclosure relates to a treatment method for coloring a metal that includes a) bombardment of the metal with a beam of singly- or multiply-charged gas ions produced by an electron cyclotron resonance source; b) heat treatment in ambient air so as to color the implanted metal using a temperature between 100° C. and 400° C. and an exposure time of between 1 minute and 4 hours.
Claims17
A treatment process for coloring a metal, comprising:
- a) bombarding the metal with a beam of mono- and multicharged ions of a gas produced by an electron cyclotron resonance (ECR) source, wherein:
- a dose of mono- and multicharged ions of the gas implanted per unit of surface area by the bombardment is in a range of between 1016 ions/cm2 and 1019 ions/cm2,
- an acceleration voltage is in a range of between 5 kV and 1000 kV;
- and
- b) performing a heat treatment for coloring the implanted metal, wherein:
- the heat treatment is performed a temperature of between 100° C. and 600° C. for an exposure time of between 1 min and 4 hours.
