Surface finishWikipedia

Surface finish also known as surface texture or surface topography is the nature of a surface as defined by the three characteristics of lay surface roughness and waviness. It comprises the small local deviations of a surface from the perfectly flat ideal (a true plane).. Surface texture is one of the important factors that control friction and transfer layer formation during sliding.

Honing (metalworking)Wikipedia

Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive stone against it along a controlled path. Honing is primarily used to improve the geometric form of a surface but may also improve the surface texture.. Typical applications are the finishing of cylinders for internal combustion engines air bearing spindles and gears.
