Surface saturation of steel with carbon increases its hardness and wear resistance. This process is called cementation. With its help, at home, you can significantly improve any steel tool made from a low-quality alloy.

To effectively protect steel surfaces from corrosion, bluing, passivation and copper plating are used. Such coatings are highly resistant to abrasion, which is superior to paint. Carry out bluing, passivation or copper plating of steel

Old tools and durable steel products become covered with a layer of rust or simply darken over time. You can renew their appearance and protect them from further destruction by applying a layer of zinc. This can be done at home without

Copper plating is used to protect steel surfaces from corrosion and give them a decorative effect.There are several ways to make it at home, the simplest of which is to use copper sulfate and a solution

With this simple but reliable method of metal etching, you can mark similar elements of a set, put a name or logo on an instrument, make an inscription on a gift, etc. Its implementation will not require large expenses, a lot of time and special skills.

While repairing my car, I was faced with the need to protect body parts from rust, while the materials available to me were either expensive or not effective enough. After several days of searching, the question arose, what’s stopping me from cooking?

Galvanization perfectly protects the car body from rust, since zinc is more resistant to atmospheric influences or mechanical and chemical influences than steel. You can apply zinc yourself using the galvanic method, but do not forget about technique

Refrigerators of various designs are used to equip the distiller. The most convenient are flow-through devices that allow efficient condensation of steam into liquid in a small volume. Let's analyze the design of an inexpensive homemade

You can purchase polymer clay for repairing small plastic parts with virtually no problems. Any colors, volumes and compositions.With its help you can not only repair damaged plastic parts, but also make, for example,

Silicone seals and gaskets, like rubber ones, can withstand pressure up to 10 bar, but in terms of temperature they are more “hardy” and work stably in the range from -50 to 280 degrees Celsius, whereas for rubber products it is limited

Hello, today we’ll talk about distillation. This is distillation, the evaporation of a liquid followed by cooling and condensation of vapors. Accordingly, the product is the distillate or residue.

Probably every DIYer or DIYer already knows that if you sprinkle super glue with soda when gluing something together, the joint will be much stronger. But is this really so? What happens to superglue when it gets mixed with baking soda?

This white inorganic powder is found in every kitchen. Despite its simple chemical formula (NaHCO3) and low cost, it can replace many household medications. It is commonly used as a leavening agent in baking or as a cleaning agent.

This amazing experiment can be repeated by almost everyone. With it you can easily surprise your friends or acquaintances.Yes, and getting to know the metal that melts from the heat of human hands will be very interesting and

Gasoline is a highly flammable liquid due to the fact that it is obtained from petroleum fractions with a low boiling point. Gasoline not only burns well, but its vapors also ignite very well, so leave containers with it open.

Sometimes, after purchasing a hand tool, it turns out that it is of low quality due to flaws in the hardening at the factory. Let's consider a method of heat treatment of screwdrivers, chisels, drills, knives, etc. at home. But it should be noted that hardening

Files, like any other cutting tool, become dull over time as the cut wears out and becomes clogged with particles of the material being processed, fat and oil deposits, dirt and other undesirable ingredients. How quickly and

The need for a source of thermal energy may arise in the home workshop, at work or on a hike. Is it possible to make it from scrap materials quickly and still ensure fire safety? Let's try.

Over time, even products made from tool steel with alloy additives rust, especially if they are rarely used and stored in an insufficiently dry and ventilated place. How to remove rust from tools if it does

The manufacture of casting products using modern materials has become quite accessible, quite simple and low-cost. Consider the option of using polyurethane for pouring and silicone to create the mold.

Many have tried to remove rust with acid solutions, usually leaving the part in the bath overnight. This is an effective method, but time-consuming. Let's look at how you can remove rust faster.

Smart plasticine, also known as hand chewing gum, is one of the most popular polymer children's toys for developing finger motor skills. Even adults are guilty of playing with him. Let's consider a way to give smart plasticine magnetic

Radiation is very dangerous for humans, but without special equipment it is impossible to determine its presence. When buying used building materials, scrap metal for DIY projects, or used vehicles, there is a possibility of running into items with radiation

When soldering, it is very convenient to use solder paste. You can buy it or make it yourself.When heated, homemade paste flows better than factory paste. When soldering twists, it penetrates deeper, which ensures a reliable connection. Its application
