Both of these processes are able to eradicate the oxide layer in a way that is harmless to the natural environment in which they are carried out. Yuge learned through production practice that the chemical reaction between the two corrosive liquids listed above and the zinc alloy is fairly powerful, and that the time control requirements for corrosion treatment while the machine is operating are stringent. Yuge also learned that the time control requirements for corrosion treatment while the machine is operating are stringent. Yuge also discovered that the time control requirements for treating corrosion on a machine while it was operating are very stringent. This information was gleaned from Yuge's observation that the zinc alloy and the aforementioned two corrosive liquids engage in a chemical reaction that is quite powerful. The reaction takes place when the zinc alloy is exposed to the liquids. On the other hand, if there is enough time, it will be possible to accomplish what needs to be done. Poor adhesion; if the time is allowed to continue on for longer, the dense layer that is on the surface of the base metal will corrode, which will reveal the loose layer that is underneath the dense layer. Poor adhesion. Unproductive bonding; if the current situation is allowed to persist for an extended period of time, the thick layer that is present on the surface of the base metal will corrode.
Because everyone is already aware of the significance of electrochemical degreasing as a factor that affects the bonding strength of the coating before plating, there is no need to state the obvious. In other words, the significance of electrochemical degreasing does zinc die casting manufacturer not need to be stated because it is self-evident. Because of this, it is strongly recommended that you make use of solutions that have a low concentration and a temperature that is roughly equivalent to what is considered to be the standard.

This article provides a clear and concise explanation of the effect that the plating pre-treatment and the pre-plating process have on the coating bonding strength of zinc alloy die-casting parts. An abstract version of the description can be found further on in this article. This is just one of a number of different factors that determine the coating bonding strength of zinc alloy die-casting parts; however, it is one of the most important ones. Due to the material's favorable die-casting forming performance, low material consumption during the process of forming, and high production efficiency, zinc alloy die-casting parts have seen widespread use in the manufacturing of other parts. This is one of the reasons why zinc alloy die-casting parts have become so popular. Zinc alloy die-casting parts have also been utilized in a wide variety of other applications. In recent years, die-casting parts made of zinc alloy have seen a significant surge in popularity, and one of the reasons for this trend is that zinc alloy is very durable. In zinc alloy electroplating, this is also the primary reason for the generation of scrap, in addition to products that have been altered as a result of the process. Scrap is generated when products that have been altered are removed from circulation. When products undergo changes as a direct result of the process, scrap material is produced.
On the other hand, electroplating is a process that is carried out in a way that is somewhat more difficult than other methods. The following procedures are typically carried out in the following sequence when electroplating zinc alloy die castings: electrochemical degreasing; hot water washing; cold water washing; corrosion; cold water washing; activation treatment; pre-plating; cold water washing; after plating; cold water washing. When determining whether or not a good coating adhesion can be achieved, the pre-plating treatment and the pre-plating process are the primary and most important factors to take into consideration. On the other hand, one more significant reason can be attributed to the improper selection and execution of the corrosion process before plating in the case of zinc alloy die castings. This issue can be found in the case of zinc alloy die castings. The case of zinc alloy die castings demonstrates this problem very clearly. During the process of zinc alloy die-casting, the metal is heated up, and previous experience has shown that this causes a relatively dense oxide layer to form on the surface of the workpiece. This is because zinc alloy is a reactive metal. This is because the zinc alloy die-casting parts were manufactured through a process known as die-casting, which explains why they have this characteristic. There is no way to provide a warranty or assurance that the zinc die castings coating will be of a high quality unless this condition is satisfied first. This is one of the requirements that must be satisfied before moving on.
It is highly recommended that a neutral electrolyte be utilized when carrying out the pre-plating process. It is recommended that organic additives not be included in the electrolyte in order to achieve the desired results of lowering the stress on the coating and increasing its toughness. Failing to include organic additives in the electrolyte, or at the very least, only including a very small amount of organic additives, will not produce the desired results. This is due to the fact that the incorporation of organic additives has the potential to render the electrolyte cloudy. Under the watchful eye of an informed individual, the pH level of the solution ought to be maintained within the range of 6 consistently throughout the process. The ability of the plating solution to disperse particles is hindered when the pH level is too low. As a consequence of this, either it is challenging to deposit a nickel layer in a short amount of time in the region of the workpiece that has a low current density, or the nickel layer is too thin; alternatively, the nickel layer is too thin. In both scenarios, the nickel layer is inadequately thick. When the pH level is too low, the ability of the plating solution to disperse particles is hindered. In addition, if the pH value is too high, the pre-plating layer is more likely to have slag inclusions, roughness, and the loose phenomenon.
These issues are caused by the plating layer being too loose. These problems could be the result of the plating layer having an uneven texture. The intermediate coating or surface coating that is deposited on this surface runs the risk of blistering and peeling off due to the fact that it is so thin. This danger is especially prevalent for the coating on the surface. In that scenario, the process won't have the desired outcome. When a base layer of copper cyanide is being applied during the plating process. Because of this ability, it is essential to employ pre-plating in all processes. It is possible to electroplate all of the components of the work in a relatively short amount of time with a thick layer of copper, which will prevent the base metal from corroding in the electrolyte during subsequent electroplating processes. This can be accomplished by using an electroplating solution that contains copper chloride. The application of an electroplating method known as tin plating is one way that this objective can be met.
