Chromium-plating and Resistance to Corrosion

Abstract

MR. WERNICK has performed a service in stating his experience on the degree of protection to be expected from electro-deposited chromium. Much of what he says is quite true, and indeed there is no disagreement between his experience and the guarded statements on this subject made by Mr. Evans in his book, and in my review of it to which he refers. Thus Mr. Evans states (page 208): “Chromium-plated articles which are now being manufactured in this country are said to withstand sea-water and tarnish”; and again, “The problem has been attended by many difficulties, some of which have not wholly been overcome as yet”. In my own review I wrote, “It is stated that plated articles manufactured in this way withstand corrosion.” Mr. Wernick seems to assume that Mr. Evans and I have expressed an opinion in favour of chromium more definite than is actually the case.
