Black oxide coating is the process of coating ferrous materials with a chemical coating process. It takes products, and it coats them in iron oxide. This provides many benefits. First, it reduces light reflection. This is beneficial because for products such as IR sensors, UV sensors, passive infrared detectors, etc. excess or reflected light can completely alter the results. Also, black oxide coating is beneficial because it adds thickness to steel, even though it’s microscopic, it helps maintain the sharpness of things like drills or screwdrivers. Also, it helps reduce corrosion and friction due to the oil or wax present. The wax or oil also allows for the material to be water resistant. This allows for there to be minimal rust. Black oxide coating also provides an attractive color and style to any product it is used on.
The Full Process Of Black Oxide Coating
There are three types of black oxide coating: hot black oxide, mid-temperature black oxide, and cold black oxide. First, hot black oxide coating. This includes a hot bath of nitrites, nitrates, and sodium hydroxide. The ferrous material is dipped in the bath which turns its surface into magnetite. After, the material is dipped into three tanks which contain alkaline cleaner, water, and caustic soda which is what eventually turns the material black. Finally, the material is dumped into the oil or wax which is the coating material. Now onto mid-temperature black oxide coating. This is pretty much the exact same as the hot coating technique, but the only difference is the temperature at what the product blackens at. This can be more beneficial because it doesn’t release caustic fumes due to the fact it is below its boiling point. Finally, cold coating. This process is different because it doesn’t involve oxide conversion. It uses deposited copper to alter its product. It is the simplest way to coat a material, but it rubs off easier and provides less resistance. Black oxide coating can be used for many materials such as copper, zink, and stainless steel. However, each material requires a different technique due to their- density and chemical makeup. These processes are very complex and require professionals to carry out.
Finding a Black Oxide Coating Company
Black oxide coating is extremely complex and can even be dangerous without the proper tools or materials. If you want the coating done right, you will need professionals. The coating requires mixing chemicals at extreme heat. This is not something someone can do on their own. Also, mixing chemicals can lead to many dangerous results. Chemicals have many different reactions when mixed with any type of substance, and if something were to be mixed without proper knowledge, there can be extreme consequences. If you want to invest in black oxide coating, you need to find a reliable company that specializes in it. To do so you should first investigate their website. Doing research on a company is extremely important because it lets you gauge how legit they are. You should read reviews, view their products, and learn about their techniques. Also, the company should solely specialize on black oxide coating. It is a difficult process that needs to be perfected, and if a company has other focuses it is likely that they haven’t perfected the processes. There are many companies that specialize in this process, but it is up to you to find the perfect one.
Why Should You Choose Black Oxide Coated Products?
In the end, coated products last longer. They don’t rust or corrode as easily as other materials. Their wax coatings make them resistant to water which is the main source of rust. Also, this wax coating allows the cleaning process to be much quicker. Since you don’t have to worry about harmful substances reaching the metal core due to the wax, you don’t have to spend as much time cleaning the item. Black oxide coating also gives your tools a sharper edge which won’t dull over time. This provides more accuracy and reliability with your product. These coated tools will inevitably last you a longer time which will also save you money. Investing in black oxide coated products and materials is a decision that you won’t regret.
