Wouldn t it be easy for the tank to rust over the mud

The soldiers of the company to which the tank belongs love it very much, have a deep affection for it, and almost every day someone will maintain it, and some people have always learned how to maintain the tank. So don't worry about rust.

The tank is coated with camouflage paint, which can achieve anti-rust and camouflage functions.

What's more, the materials of tanks are not necessarily all iron, which has been replaced by other metals.

Iron is rarely used in modern large-scale products, and has been largely replaced by other metals, which are stronger, lighter and ...... than iron

It is basically impossible to encounter such a problem in wartime.

I don't know what technology is used, it won't rust. When he retired more than 20 years ago, he brought back a bunch of small screws that were dismantled from the wreckage of missiles and did not look like ordinary screws, as well as some large screw mothers.

The tracks of the tank are divided into two types: casting and forging, no matter which one it is, it will not be made of pig iron that is easy to rust, not only easy to rust, but also not up to the standard in strength.

The materials used in the tank tracks are anti-corrosion, the road surface on which the tank has to walk is not only water and mud, any substance is possible, it is impossible to pull the tank out every day for military training in peacetime, the strength is far worse than this, there is no problem with maintenance in peacetime, and when it comes to wartime, maintenance is not the primary consideration.

No track with anti-corrosion layer.

The tank was painted with camouflage paint.

Done. When you say that, you can still think of what I do. Childhood, hehe, old age, there are memories left.

I usually use stain washing, stain washing is to wipe out the traces after painting, first of all, the oil paint generally only needs to be dipped in yellow, white, black, green and zippo oil in a ratio of 1:3 to dilute (note to fully stir), and then evenly apply to the model with a pen, let it stand for 10 15 minutes, and then wipe it clean with a cotton cloth and cotton swab. To be reminded of this:

Don't rub too hard, especially the edges and corners, to wipe off the paint; Sometimes the time is not well mastered, the oil paint has dried, don't wipe hard, use a cotton swab dipped in a little zippo oil to gently wipe it; It is recommended that you use the principle of "less amount and more meals", you can wash it several times to enhance the effect, and avoid making the oil paint too thick and causing it to be difficult to clean up.

a. Paint the tracks of the tank, because the friction between the rotation of the track and the ground will make the paint fall off quickly, and it cannot play a role in protecting the metal, so A is wrong;

B. The underground steel pipeline is connected to a certain number of magnesium blocks at intervals, and the activity of MG is stronger than that of FE, and FE is protected as the positive electrode when forming a galvanic battery, which can prevent the metal from being corroded, so B is correct;

c. A certain number of zinc blocks are installed in the part below the waterline of the ship hull, and when Fe and Zn form galvanic batteries, Fe is protected as the positive electrode, so C is correct;

d. Stainless steel has strong corrosion resistance, so the drum of the washing machine is made of stainless steel, which is wear-resistant and corrosion-resistant, so D is correct;

So choose A
