摘要： Golf bails include: (a) a golf bail having a first set of construction specifications; (b) a coating of the golf ball having an exterior surface and (c) the exterior surface having an enhanced micro surface roughness. The enhanced micro surface roughening affects the aerodynamic properties of the ball as compared to golf balls having the same set of construction specifications but without enhanced micro surface roughness.

摘要： Golf balls include: (a) a golf ball body having a first set of construction specifications and a first dimple pattern (18) formed on an outer surface of the golf ball body; and (b) a coating (20) applied to the outer surface of the golf ball body to thereby produce a coated golf ball body having an exterior surface. At least one of the outer surface of the golf ball body and the coating includes a plurality of surface roughening particles (22) to provide increased micro surface roughness as compared to golf balls having the same set of construction specifications and the same dimple pattern but without the micro surface roughening particles. The micro surface roughening affects the aerodynamic properties of the ball.

摘要： A golf ball is provided including a core (12), a cover (14) encasing the core and a coating (16) that comprises a resin applied to the outer surface of the cover. Particles (22) comprising a high density material are included in the coating such that the coating has a density at least twice that of the core's density or contributes at least 0.60% of the golf ball's total moment of inertia, and the coating has a micro surface roughness at least 1.75 times larger than the roughness of a comparative ball. A method of making a golf ball is also provided, including providing a spherical core, encasing the core with a cover, applying a resin to the outer surface of the cover, and adding a plurality of particles comprising a high density material to form a coating material that has a second density at least two times the first density.
