Chromed objects for people who like cromar objects, I here something to what they can do at home. Dan Miller is often quoted on this topic. Obviously we are not going to compare this with industrial chrome plating, but you can do it personally. To make a perfect chrome, you need skill and experience, but for fans we will immediately give the tips needed to do so in an excellent way, if they adhere to the instructions. For fans, there are 2 adequate bathrooms: bathroom to chromic acid: 125 grams of chromium sulfate: 1.5 grams water: 470 grams bathroom B chromic acid: 125 grams sulfuric acid: 1 gram water: 470 grams can say bath to is the one that best results yields, but their cost is higher than the bath B. Learn more on the subject from Coral Resorts. It is important that both bathrooms are made at a temperature of 38 degrees C; for this you must introduce the container that will contain the elements within another containing water heated to the temperature indicated (see figure above).
I should mention that the galvanocromicos baths are highly corrosive so it should not be using containers metal, used instead of glass, earthenware or porcelain, we recommend also using guates and avoid skin touch liquids, se should also avoid, breathe the vapors that emanate. ELECTRODES: To the positive electrode will use a tube of lead which is very clean, the negative electrode will be the object that will be chromed. If the lead pipe that will be used, was previously used in a sulfuric acid solution, it will be more efficient because that is you will have formed a peroxide of lead in surface film. The power for chrome plating should not exceed 6 volts of direct current, but its amperage must be considerable, if possible, reduce and rectify the current of 110 volts to 6. You can use is also a 6 Volt car batteries (accumulators) in parallel to obtain the necessary amperage. Time needed to make chrome the object is half an hour, in this period of time it is suitable that you stir the solution frequently.
DEPOSITS of chrome: If the current was supplied appropriate, the chrome layer which deposited in the object will be bright and need polishing. If on the contrary, the current was very low, chromium plating will be opaque. Then, we must take into account that adequate power is responsible for a polished chrome. If the draught is too strong, chrome will be a dull grey color.It is possible also, that the results are not as desired, if the bath solution and the temperature was altered. This leads us to think that the success of the galvanocromia, is to adhere to the instructions above. Practice will give you the necessary experience. It is obvious that objects to cromar must be cleaned as such, that not them fat before placing them in the bathroom, since the slightest amount of this will make chrome will not adhere. Finally, the metals that you can cromar sn as follows: brass silver, copper. If you go to chrome iron or steel, previously have to soak in a bath of copper or nickel so that the surface is in good condition to be chromed.
