One of the ways to restore a failed precision mechanical part is to use thermal spraying. First of all, the surface of the workpiece needs to be pretreated, and the degree of bonding between the coating and the base material (workpiece material) is the key. If the bonding cannot be performed or the bonding strength is not enough, the spray coating will be peeled off from the substrate, failing to ...

Electroless nickel plating technology is a method in which metal salts and reducing agents are used to obtain coatings by autocatalytic reactions on the surface of materials. So far, electroless nickel plating is one of the fastest growing surface treatment processes and has the widest range of applications. It can make the machined precision parts more wear-resistant and durable. The rapid develo...

The last article introduced what is electroless nickel plating, and this article will introduce the related process of nickel plating. Electroless nickel plating and electroplating nickel are both nickel plating processes, but they are very different. 1. The principle difference between electroless plating and electroplating is that electroplating requires additional current and anode, while elect...

The definition of the burr Burr is a protrusion of a material, such as metal or resin that is generated when it is processed. Burrs are created from shearing, bending, cutting, piercing, and compressing materials that are mostly seen on soft and ductile materials. About the burr size, we express burr size by its height, thickness and length. And the deburring is a secondary operation of a machinin...

Cleanliness refers to the amount of contaminants remaining on the surface of a part or product after cleaning. The indicators of dirt include type, shape, size, quantity, weight, etc. The specific indicators used depends on the degree of influence of different contaminants on product quality and the requirements for the accuracy of cleaning control. The purpose of ensuring the cleanliness is to en...
