Abstract
An improved rotor shaft for a vibratory dental scaling instrument. The shaft includes a metal substrate having a surface layer of nickel-boron alloy. The alloy surface layer provides a durable bearing surface for a rotor rotatably mounted on the shaft. The thus fabricated scaling instrument is capable of being heat sterilized without adverse effects on its rotary components.
