Ultrasonic and Hardness Study of Low Contractile Chromium Deposited in the Flow-Through Vessel Plating Facility.

Abstract

The elastic properties and the yield strength of electrodeposited chromium are among the properties that determine its usefulness in corrosion and erosion protection as a coating in gun tubes. The determination of elastic properties of electrodeposited chromium, through careful measurement of ultrasonic velocities, is the main subject of this report. The elastic properties are also correlated with the coating Knoop hardness as a function of plating process parameters (current density and electrolyte flow rate). These studies can lead to a better understanding of the mechanisms involved in the deposition by observing how changes in process parameters influence the properties of the electrodeposited coating. p4
