WHAT IS THE GENERAL THICKNESS OF CHROME PLATING FOR HYDRAULIC CYLINDER RODS?

 As we all know, the thickness of the chrome plating much related to the working life of the industry hydraulic cylinder ,As a professional manufacturer of hydraulic cylinder ,we usually will receive the requirements that customers ask chrome layer thickness of the hydraulic cylinder rod, 20/25/30/50 Micron or customized can available for us.

Hydraulic cylinder piston rod chromium plating layer is not thicker, the better, the reasons:
1, chromium coating in the process is reciprocating multiple coating, that is, the single coating amount is about 0.03-0.06, and the coating effect on the substrate surface is better, the secondary coating effect on the already coated surface is not good, easy to produce delamination, off the skin small defects, and the hydraulic system is the most taboo there are such defects;
2, when the coating thickness reaches more than 0.10, the domestic is not good, not can not be done, but is not necessary in the use of special occasions.
3, supplement: plating process can achieve 0.15-0.20 coating thickness;

hydraulic cylinder rods


Coating thickness should vary according to the use of different occasions. When the mechanical load is light and general protection, the thickness is l0 ~ 20μm; When the sliding load and the pressure is not too large, the thickness is 20 ~ 25μm; When the mechanical stress is large and the corrosion resistance is strong, the thickness is as high as l50 ~ 300μm; For the piston rod, this thickness is generally enough for hard chrome plating, even taking into account other aspects of the requirements, although the proposed thickness can be achieved, but for the outer circle, the chromium layer is a little thick, the coating binding force is higher, and the plating is more difficult. For the piston rod exposed to the outside, the chromium layer that is too thick is not as resistant to bumping as the thinner chromium layer.

How to deal with the scratch on the surface of hydraulic cylinder barrel

Image
As we all know,In the process of using the  hydraulic cylinder , the hydraulic cylinder barrel will be damaged,it is common that there will be scratch on the surface of the  honed tube , some customers will ignore these scratches, this to us is not responsible for the cylinder, when a small scratches in the cylinder,we usually take some tips to deal with them. 1.First,  to clean up the oil on the surface of our hydraulic cylinder barrel, then we will use the grinder machine to the surface treatment of the scratched part of our cylinder, at this time we have to grind the surface of the cylinder wall out of swallowtail groove. Although we have cleaned our cylinder at the beginning, at this time we need to clean the cylinder barrel further. At this time, we use anhydrous ethanol to clean the surface of the scratch repair of honed cylinder barrel. 2. We usually use special  repairing adhesive  to solve the scratches on the surface of  hydraulic cylinder barrel ...

Heat Treatments Of Seamless Steel Tube

Image
Heat treatment of  seamless steel tubes  is a process to improve the properties of metal materials and their products. Depending on the use, the material and its workpiece are heated to the appropriate temperature, insulated, and then cooled in different ways to alter the internal structure to achieve the desired performance. Heat treatment of seamless steel tubes is generally divided into annealing, normalizing, quenching, tempering, failure, chemical heat treatment and vacuum heat treatment. By heat treatment, the efficiency or life of the steel can be improved, and in some cases, more expensive special materials can be used instead of cheaper ordinary metal materials. The basic heat treatment methods of seamless steel tubes mainly include the following four forms: 1. Annealing Annealing is a process in which a seamless steel tube is heated to a slightly higher or lower critical temperature for a period of time (ie, heat preservation) and then slowly cooled. Common annealing...

HOW TO REPAIR THE HYDRAULIC CYLINDER ROD

  Hydraulic cylinders can be repaired, but you should never attempt these repairs on your own. Although hydraulic cylinders have a simple design, you must be familiar with them in order to efficiently repair them. When a technician performs hydraulic cylinder repairs, they take the entire mechanism apart and reassemble to find the root cause of the issue. COMMON POINTS OF HYDRAULIC CYLINDER FAILURE There are several common points of hydraulic cylinder failure. These include the piston, cylinder rod , seals, and head. PISTON The pistons in hydraulic cylinders are one of the most common points of failure. This is especially true in light-duty applications. The pistons used in light-duty applications are often made from aluminum, which wears out much more quickly than the steel used in heavy-duty applications. When checking pistons for failure, technicians will often measure the diameter of the piston. The piston’s diameter in relation to the bore directly affects the amount of hydra...
