Claim:
1. A method of making a calcium-fluoride layer formed on an object surface for more wear resistance, comprising steps of: coating sodium fluoride to a surface of an object having calcium, whereby after a chemical reaction, the sodium fluoride and the calcium are inverted to become a calcium-fluoride layer on the surface of the object; preparing a laser device having a laser emitter for emitting laser; and applying irradiation of the laser to the calcium-fluoride layer via the laser emitter for at least five seconds, whereby the wear resistance of the calcium-fluoride layer is enhanced and absorption of the fluoride on the object is increased; wherein in the second step, the laser device further comprises a programmable logic controller (PLC), a three-axis mechanical arm, a charge-coupled device (CCD) camera lens, a data processing device, and a display, all of which are electrically connected with one another, the laser emitter and the CCD camera lens being fixed to the Z-axis of the three-axis mechanical arm, the three-axis mechanical arm being controlled by the PLC, whereby the CCD camera lens captures an image of the object and immediately transmits it to the data processing device, and after the image is processed, a positioning control based on laser dotting is applied onto the display.
