Abstract
A handbell has a bell body with an inner surface engageable by a clapper to produce a sound corresponding to a note of the musical scale and an outer surface with a vapor deposited nitride layer that resists tarnish. Preferably, the vapor deposited nitrate layer has a thickness of less than about 5 microns and does not adversely affect the sound produced when the handbell is rung. In addition, preferably the vapor deposited nitrate layer is zirconium nitride or titanium nitride and has a Vickers hardness (HV) of at least 2300. A method of making and/or refurbishing a handbell is also disclosed.
