The Relationship between roanoscale AFM adhesive force measurements using calcite crystals with macroscale contact angle and scaling characteristics

The strength of calcite adhesion to various surfaces was measured using atomic force microscopy. This nanoscale measurement was compared to both macroscale work of adhesion, as determined by contact angle measurements, and the rate of scale formation, calcite begin the major component. A broad correlation is seen in both cases. Possible causes of deviation between adhesion measurements and the macroscale observations include affect of and impurities in the measuring media. Also distribution of adhesion forces played an important role when comparing adhesion forces with scaling measurements.
