The current research aims to study the effect of chemical disinfectants
on the roughness and hardness of the surface of the cobalt chrome
alloy, where the use of cleansing Sodium hypochlorite 5.25%
and distilled water (the control sample), Been ma
nufacturing 20
structure metal of the alloy cobalt chrome, each group containing 10
samples and was doused with samples intravenously cleared, then it
was measured surface roughness using an Atomic force microscope, and
measuring the hardness of the surface using a Vickers measuring device
hardness.
