  • Publication number: 20160135937
    Abstract: A method of making a calcium-fluoride layer formed on an object surface for more wear resistance includes the steps of coating sodium fluoride to a surface of an object having calcium, whereby the calcium fluoride and the calcium are inverted to become a calcium-fluoride layer on the surface of the object after a chemistry reaction; preparing a CO2 laser device having a CO2 laser emitter for emitting CO2 laser; and applying irradiation of the CO2 laser via the CO2 laser emitter to the calcium-fluoride layer for at least five seconds. In light of this, the wear resistance of the calcium-fluoride layer is enhanced for at least 34%, the absorption rate of the fluoride is increased for at least 23%, and the surface of the object has aesthetic and integral appearance.
