    How much do you know about the quenching process? Part 1

    It is well known that heat treatment is a common method for changing the mechanical properties of certain metals. Being able to change the hardness, toughness, and strength of a metal while keeping its chemical composition intact and nearly unchanged is a great way to tailor a metal to the needs of the environment and job. There are many different ways to heat treat metals, the most popular of whi...

    How to restore a failed precision mechanical part?

    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 ...

    What is the difference between electroless nickel plating and electroplating nickel?

    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...

    What is the deburring for precision machining?

    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...
