For example, a threaded joint with a strong lube movie has actually been suggested as a choice to threaded joint without substance grease. Nonetheless, this technique has actually not been fully confirmed. In fact, it is challenging to make sure a good bond between the strong lubricating substance and the lubricating movie. In addition, the film may create a reduction in the coefficient of rubbing of the contact surface areas. For this reason, it is essential to ensure that the film consists of the right amount of strong lube.
Among the solid lubes, molybdenum dialkyl thiophosphate, calcium stearate as well as molybdenum dialkyl sulfate have actually been utilized as instances. The typical fragment size of the solid lube is ideally a minimum of 0.005 micrometers. It is extremely difficult to uniformly spread particles with an average bit size of more than 3 micrometers. The mass proportion of solid lubricating substance must be at least 0.3. In addition, the content of the solid lubricating substance should be at least 9.0 mass percent.
Nevertheless, the result of the mass ratio on the enhancing lubricity of the lubricating movie is fairly tiny. For instance, the lubricating film of the Japanese Published Unexamined Patent Application Hei 8-233164 contains molybdenum disulfide as one part of the not natural compound with Ti-- O foundation. The various other part was a graphite powder.
In addition, the overall base number of the lubricating movie need to go to the very least 15 mgKOH/g. This number is very important since corrosion easily creates when the complete base number is much less than 15 mgKOH/g. Nevertheless, the coefficient of friction enhances with the overall base number.
Lubricity of a phosphate movie
Throughout the years, molybdenum disulfide has actually been the topic of much research. This material is an effective lubricating substance, providing deterioration avoidance, high return strength and low rubbing. It is additionally utilized in bit lubrication.
