Gold is a high-quality hedge hedging tool, favored by investors. Especially in recent years, with the increasing instability of the world economy, gold has become one of the preferred asset allocations of investors because of its functions of hedging and fighting inflation.
Earlier, the worsening situation in Ukraine sent gold prices soaring to a two-year high of $2,070 an ounce. But gold, along with other commodities, fell back last week as conditions changed and bulls took profits, hitting a low of $1,895 an ounce. Rising gold prices may also have an impact on the Chromium carbide (Cr3C2) prices.
According to China Business News, Goldman Sachs raised its gold price forecast in early March, considering Asian buyers' gold consumption demand, investment demand and central bank gold purchase demand continue to rise. Three -, six - and 12-month targets were raised to $2,300, $2,500 and $2,500 an ounce, respectively, from $1,950, $2,050 and $2,150. The last time all three accelerated was in 2010-11 when gold prices rose nearly 70%.
The World Gold Council has also noted that global gold demand is at its highest level in nearly two years, which is linked to a recovery in consumption and consumer sentiment to combat inflation.
Overview of Chromium carbide
Chromium carbide (Cr3C2) is a refractory ceramic compound. As the name implies, chromium carbide is a combination of chromium and carbon. Chromium carbide has high hardness, high strength and good corrosion resistance.
Chromium carbide has many uses. Due to its high hardness and corrosion resistance, it is used as a wear-resistant coating. Because it is a refractory material, it can maintain good wear resistance even at high temperatures. Another application is as a grain growth inhibitor. When producing other types of carbides, chromium carbide is used as an additive to help prevent excessive grain growth and improve the toughness of the carbides.
Chromium carbide is also formed by intergranular corrosion. When certain types of stainless steel are heated to the extent that chromium can bond with carbon atoms, intergranular corrosion will occur. This reduces the amount of chromium and chromium oxide available, thereby preventing corrosion. This process is called sensitization. However, when this occurs on stable grades of stainless steel, it is called knife mark corrosion. In these cases, chromium carbide is usually not desirable because it is not conducive to the corrosion resistance of certain stainless steels.
Applications of Chromium carbide
Chromium carbide powder is a high melting point material with good wear resistance, corrosion resistance and oxidation resistance in high-temperature environments.
Chromium carbides are hard, and their general purpose is to provide hard wear-resistant coatings on parts that need protection. When combined with a protective metal substrate, corrosion-resistant and wear-resistant coatings can be developed that are easy to apply and cost-effective. These coatings can be applied by welding or thermal spraying. When combined with other carbides, chromium carbide can be used to form cutting tools.
Chromium carbide welding electrodes are increasingly replacing older chromium-containing ferrochrome/carbon welding electrodes because they provide better and more consistent results. In welding electrodes containing ferrochrome/carbon, chromium carbide is formed during the welding process to provide a hard wear-resistant layer. However, the formation of carbides is determined by the precise conditions in the weld. Therefore, there may be changes between the welds, and this change is invisible in the electrode containing chromium carbide.
The trend of the welding industry from using rod electrodes to flux-cored wires is benefiting chromium carbide. Chromium carbide is almost exclusively used for flux-cored welding wire, not high-carbon ferrochrome because it is not affected by the dilution caused by excess iron in high-carbon ferrochrome. This means that a coating containing a large number of hard chromium carbide particles can be produced, which exhibits greater wear resistance. Therefore, the market for chromium carbide has increased due to the conversion from rod electrodes to flux-cored wires due to the benefits of automation and higher productivity associated with flux-cored wire welding technology.
3.Thermal spray application
In thermal spray applications, chromium carbide is combined with a metal matrix such as nickel-chromium. The weight ratio of carbide to the metal matrix is usually 3:1. The metal matrix is present to bond the carbide to the coated substrate and provide a high degree of corrosion resistance. The combination of corrosion resistance and wear resistance means that thermal sprayed CrC-NiCr coatings are suitable as a barrier to high-temperature wear. Therefore, they have found more and more applications in the aerospace market. The typical use here is as a rod mandrel, thermoforming mold, hydraulic valve, coating of mechanical parts, wear protection of aluminum parts, and good corrosion and wear resistance at temperatures up to 700-800°C The general application.
The new application of thermal spray coating is an alternative to hard chrome plating. Hard chrome plating can produce wear-resistant coatings with a good surface finish at a low cost. The chromium coating is obtained by immersing the object to be coated in a tank of a chemical solution containing chromium. Then, the current passes through the groove, causing chromium to deposit on the part and form a coherent coating. However, environmental problems related to the treatment of waste liquid is used electroplating solutions have become increasingly serious, and these problems have led to increased process costs.
The wear resistance of the chromium carbide-based coating is twice to five times that of the hard chromium coating, and it will not encounter wastewater treatment problems. As a result, they found that the use of hard chromium coatings was increased at the expense of hard chrome coatings, especially where wear resistance is important or where thick coatings are mostly required. This is an exciting and rapidly evolving field, which will become more and more important as the cost of complying with environmental regulations increases.
The main material in cutting tools is tungsten carbide powder, which can be sintered with cobalt to make extremely hard cutting tools. In order to improve the toughness of these cutting tools, titanium carbide, niobium carbide and chromium carbide are added to tungsten carbide. The role of chromium carbide is to prevent grain growth (a form of grain refinement) during the sintering process. Otherwise, too large crystals will be produced during the sintering process, which will be detrimental to the toughness of the cutting tool. It is no exaggeration to say that without additives, modern cutting tools will not achieve their current performance.

Because of the conflict between Russia and Ukraine, there is a shortage of natural gas supply. At the same time, other renewable energy sources cannot produce enough electricity, so electricity prices have soared in many countries of the world. For this reason, I assume the supply and prices of the Chromium carbide (Cr3C2) would keep being influenced by the high energy prices.
