What is chrome?

Chrome is a metal. It is hard and brittle and highly resistant to corrosion. It is silvery white, and after polishing it acquires a shine. It is a poor conductor of electricity and heat. Chromium cannot be found in nature as a metal. It is found in several minerals, most of them brightly colored, but chromium is isolated from only one mineral. It is a heavy black mineral called chromite.

The largest deposits of this mineral are found in South Africa, Russia, the Philippines and Zimbabwe. Many of us only know chrome because it is used as a shiny finish on car bumpers and other metal objects. But in reality, the most important use of chromium is in steel alloys. With the addition of a small amount of chromium, the steel becomes stronger, harder and more resistant to corrosion.

Chromium is an important part of stainless steel as stainless steel is widely used where corrosion resistance is required. For example, chromium-plated stainless steel is used to make knives, forks, spoons, saucepans, kitchen sinks, counters, tools, dairy equipment, and even surgical instruments.

Chrome is used to give a shiny finish to metal objects. This coating is obtained in a process called electroplating. Chrome plating was first used to decorate and protect watches, jewelry and household items. Car makers started making it on bumpers and interiors around 1925.

Nowadays, chrome plating is used primarily in the automotive industry. Parts of machines that are subject to the most wear and friction, such as gears and support surfaces, are often chrome plated. Such chrome-plated moving parts can operate without oil lubrication. Chromium salts are used for tanning leather and dyeing fabric. Many brightly colored chromium constituents are used in paints. So, you see that chromium is one of the most useful metals for humans.

Random interesting fact from the Great Encyclopedia:

Where did the tradition of eating donuts come from among American police officers?

According to a stereotype, primarily a cinematic one, American policemen love donuts most of all. This tradition dates back to the post-war years. Police officers often have to work the night shift, and at that time, almost the only catering establishments that worked at that time were just donut cafes. The owners of some of these points even offered special conditions for law enforcement officers, as their periodic presence gave peace to the night staff.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Volvo self-driving trucks for sugarcane harvesting 12.06.2017

In the cultivation of sugar cane, it is important not only to grow a large crop, but also to properly organize its collection so that when the product is taken out of the fields, it does not damage the soil and young plants, which will become the basis of the next year's crop.

Volvo Trucks has developed a self-driving truck that is expected to help increase the sugarcane harvest in Brazil. The truck will be used to transport the newly harvested sugar cane. Controlled by the autopilot system, it adheres to the set course with great accuracy, which helps to protect the cane sprouts from damage.

The system predominantly controls the steering using two gyroscopes to prevent the vehicle from deviating more than an inch (25 mm) from its set course. The GPS navigation system is used to track the route through the field, and the driver can set a constant speed with the help, slowing down or accelerating as necessary.

Currently, about 4% of the crop is lost due to damage to sugarcane sprouts, as well as due to soil compaction when vehicles move across the field. The use of autonomous trucks will avoid significant damage to soil and crops, increasing yields of up to 10 tons of sugar cane per hectare per year.
