Abstract
Purpose: In this paper, the changes in eyeglasses frames were investigated when the frames were exposed toartificial sweat. Methods: The changes in surface, hardness, and tensile strength of eyeglasses frames made ofnickel silver, Monel, and titanium were tested after the exposure to the artificial sweat of pH 6.5, 6.0, and 5.0,during 1, 3, and 6 week(s), for each. Results: Corrosion pattern of eyeglasses frames made of nickel silver,Monel, and titanium was induced by artificial sweat, and the patterns were different from another frame materials.
In proportion to the pH of artificial sweat and exposure time to artificial sweat, hardness of all frames made ofthree different material decreased, however, tensile strength of the three frames was not changed. Conclusions:The necessity of routine management for eyeglasses frames can be suggested since the changes in surfacecorrosion and hardness of eyeglasses frames induced by sweat were shown.
