Anonymous users2024-02-06The Mercedes-Benz logo is made of chrome material.
Chromium is a silvery-white metal with a microstrip blue, with a relative atomic mass of 51 99, a density of 6 98 7 21g cm3, a melting point of 1875 1920, and a standard electrode potential of Yush C, -0 74V, old "C," -0 41V and P even E+ Cr jitter -1 33V, metallic chromium is very easy to passivate in the air, and a very thin passivation film is formed on the surface, thus showing the properties of ***.
The chrome plating layer has a high hardness, which can vary in a wide range of 400 to 1200 HV depending on the composition of the plating solution and the process conditions. The chrome plating layer has good heat resistance, heated below 500, its gloss and hardness have no obvious change, the temperature is greater than 500 and begins to oxidize and change color, and the hardness is greater than 700 and begins to decrease. The coefficient of friction of chrome plating is small, especially the coefficient of dry friction, which is the lowest of all metals.
So the chrome plating layer has very good wear resistance.
Chromium plating has good chemical stability and does not act in alkalis, sulfides, nitric acid and most organic acids, but is soluble in hydrochloric acid (e.g. hydrochloric acid) and hot sulfuric acid.
In the visible light range, chromium has a reflective capacity of about 65%, which is between silver (88%) and nickel (55%), and is better than silver and nickel because chromium does not change color and retains its reflective ability for a long time when used.
