Mechanical Testing of Calcium Phosphate & …

Adhesion strength (or cohesion strength) measurements of calcium phosphate coatings and metallic coatings are based on the results from static and fatigue loading of standard test coupons. Specifically, two coupons – one coated and one uncoated – are mated together via an adhesive (e.g. FM-1000), and cured in an oven under constant temperature and force.

arrange the elements in the increasing order of …

Metallic character refers to the tendency to loose valence electrons. Down the group, atomic size increases due to which the tendency to loose electrons increases. On moving left to right in a period, the atomic size decreases due to which the metallic character decreases. Thus the order of increasing metallic character is as follows: Mg < Ca < Na

METALLIC CHARACTER & CHARACTERISTICS - …

Metallic character is the chemical properties of metal elements, which is determined by the level of difficulty in losing their electrons. Going across the periodic table from left to right, metallic character decreases. This is because atoms are more accepting of gaining electrons to fill their valence shell.
