Preference changes, some people are happy and some people are sad.
WoodMac expects that rebuilding trust will take time, and trading volumes are unlikely to recover immediately. "All price indices of affected commodities will be subject to increased scrutiny." Meanwhile, Fitch Solutions Country Risk and Industry Research said that as nickel prices rise and battery manufacturing costs soar, consumers of high-grade nickel seek Alternatives supplied by Russia.
Russia is the leading supplier of Category 1 nickel ore, while China is the most important player in the refining industry. Fitch said in its new report that automakers, battery makers and industrial consumers are likely to forge new business partnerships to source high-grade nickel alternatives, as supplies from Russia struggle against the backdrop of the Russia-Ukraine conflict. still restricted. To this end, China Tsingshan Group and other companies actively developing low-grade nickel refining capacity will benefit.
Fitch also noted that shifting importer preferences, sanctions and a desire to minimize sanctions risk are affecting purchases of Russian nickel exports. Therefore, mining and refining operations in "safe" countries with more stable regulatory and trade regimes may benefit. At present, the anodic oxidation of titanium and titanium alloys is mainly carried out in an acidic solution. The color, thickness and performance of the obtained oxide film are different depending on the anodizing solution and process conditions.
The main methods are oxalic acid anodizing, pulse anodizing, thick film anodizing, and color anodizing. When the anodized film of titanium and titanium alloys fails to meet the requirements, it also involves the removal of the anodized film of titanium and titanium alloys. The following is an introduction to colored anodizing:
The color of titanium surface is not only useful in production, but also has certain artistic value. Under proper anodic gasification conditions, the transparent oxide film formed on the surface of titanium, which is easy to form interference color, will produce a color rich in artistic value. potential applications.
When the current passes through the titanium anode suspended in the electrolyte, the oxygen generated on the titanium anode reacts with titanium to form an oxide film, the thickness of which increases with the increase of the voltage, and at the same time, the hindering effect of the oxide film on the current also increases. . A certain voltage corresponds to a certain thickness of the oxide film, and the color of the oxide film changes with the thickness of the oxide film.
