I don’t think so. It’s possible the abrasion I have noticed in the past had another factor like metal allergy I’m not aware of.
If I remember right, chrome plating is made by depositing a layer of copper and then chromium on metal, usually electrostatically. Aside from the metal allergies that could come from the plating, both copper and chromium are reactive metals that can cause issues on their own in the body. From a toxicological point of view, copper 1+ and 2+ are pretty biocompatible, the body knows how to handle them and remove excess from the body. Copper 1 readily converts to copper 2. Chromium on the other hand has many oxidation states, some that are fine in certain amounts (Chromium 3+), but others are highly toxic (Chromium 6+).

I’m not sure which ions are produced and at what concentrations when chrome plating reacts to the skin. Given the skin sweat as a solution you couId probably expect to have a spectrum of chromium oxidation states due to reactions with oxygen and salts. I could guess how about the stoichiometric ratios by looking at some known reactions by pH and the resulting salts, but you’d really have to test it to be sure. Trying to anticipate the outcome of elements in the D-block (electrons populating the D orbitals) is really complicated because there are quite a few stable configurations for the electrons in that orbital shell.
