Having a nickel boron coating on your firearms is a smart choice, because it gives them a tough and protective finish. This is ideal for any kind of firearm, including shotguns and rifles. Unlike other coatings, nickel boron coating will not fade with exposure to heat, chemicals, or air, and will remain strong for a long time.

Ship Propellers

Among the many benefits of electroless nickel boron plating, one is its ability to provide anti-corrosive protection to ship propellers. This coating helps to minimize stress and minimize wear, as well as improve cleaning. In addition, the coating offers a slightly increased surface durability.

Electroless nickel boron plating has become a popular process in the oil and gas industry. It can be applied to various ship components and is relatively quick and easy to perform. During the process, a thin layer of nickel boron coating is deposited onto a solid substrate. It offers a durable coating and is easy to clean.

The effects of counter rotation on propeller wakes were investigated using flow measurement and numerical simulation. A two-blade counter-rotating propeller and a four-blade SRP were used to compare the effects. The results indicate that the four-blade SRP has a higher efficiency than the dual 2-blade SRPs.

In addition, several attempts have been made to modify the geometry of the propeller tip. However, these attempts have failed to fully resolve the tip vortex. Therefore, the present invention aims to address the problem.

The method involves a cyclical model which is simplified by making an assumption of constant angles of incidence. It is validated using experimental results for a pair of propellers operating in five different wake fields.


Traditionally, the firearm industry has used Nickel Boron coating on firearms. The coating protects the gun from wear and tear while also providing superior corrosion resistance. It also offers increased wear protection and reduced friction.

While the firearms industry has largely migrated away from traditional hard chrome plating, there are still some parts that require the use of a hardcoat. For these parts, the best finish is a Nickel Boron coating.

While a nickel boron coating is much more expensive than a traditional plated finish, it provides superior corrosion resistance and wear protection. The coating is chemically applied, and will not peel or chip the base metal. The coating will provide a uniform surface finish that will not affect threaded edges or critical edges.

The benefits of a nickel boron coating are excellent, and there are a number of companies that offer this type of coating. For example, WMD Guns has been a leader in the field of nickel boron coatings. WMD has developed a high-end nickel boron coating called "NiB-X."

NiB-X is designed to reduce friction. It features micro-domes and uniform nickel boron. These micro-domes create a topological texture that reduces the contact surface area. Unlike traditional hard chrome plating, NiB-X does not coat the metal with an additive.

Electroless Nickel-Boron Plating

Platers turn to electroless nickel plating when they want to coat a part with a hard coating. This is done for a number of reasons. For one thing, the boron content in electroless nickel-boron deposits is higher than that in phosphorous-based coatings, resulting in a harder surface. It also has better abrasion and wear resistance.

Electroless nickel-boron plating is used in a number of industries, including the oil and gas industry. The plating can be used for self-lubrication, anti-corrosive protection, and decoration. It is also used for prototypes and mold surfaces. It is RoHS compliant, and meets Mil-Spec standards.

Electroless nickel-boron plating works by depositing a thin layer of nickel-boron coating on a solid substrate. It can be used to coat parts with a thickness of up to 15 feet. This coating has a surface texture that is similar to hexavalent hard chromium.

Electroless nickel-boron deposits can be produced in baths that contain borane reducing agents. These baths are very harsh. They operate at a temperature of 90degC and lay down deposits of high-boron.

However, conventional electroless nickel-boron deposits contain toxic heavy metals. They have also been subject to scrutiny because of recent environmental concerns. The use of thallium as a stabilizer in commercial processes has raised concerns about disposal.
