At the NIST Combinatorial Methods Center, the multilens combinatorial adhesion test (MCAT), based on the Johnson, Kendall, and Robert (JKR) contact mechanics, has been developed to quantify the work of adhesion between an elastomer lens array of numerous probes and a transparent substrate consisting of a property gradient of interest. The JKR test provides the work of adhesion and system modulus of an elastic hemisphere brought into contact with a curved or flat plane by measuring the applied load, displacement, and contact area. The development of this high throughput adhesion test has presented a unique set of challenges concerning instrument design, image analysis, and data mining. Recent developments in data analysis will be discussed, with a focus on model roughness gradient system.
