Problems solved by technology

[0003] Magnesium alloys have low material hardness and poor anti-corrosion and anti-rust properties. The current treatment methods are mostly surface spraying anti-corrosion materials and anodization. The problem of weak bonding between the material and the substrate is prone to fall off, and the hardness of the material is low. The vehicle is scratched by hard objects such as stones

Abstract

The invention discloses a magnesium alloy vehicle hub surface treatment process, and in particular discloses a ceramic treatment formula and process for surface treatment of a magnesium alloy vehicle hub. The process comprises the following steps: 1, cleaning a hub workpiece by using a metal detergent to remove greasy dirt; 2, adding a prepared crystal procelainization solution into a treatment solution tank, applying a positive electrode to the treatment solution tank, and applying a negative electrode to the workpiece, wherein the power supply adopts an alternating power supply; 3, installing a circulating cooling water pipe for controlling the temperature of a crystal procelainization solution outside the treatment solution tank, wherein the temperature of the crystal procelainization solution is below 40 DEG C; 4, performing crystal procelainization for 40 minutes under the condition that the power supply voltage is 160V, the current is 100A and the alternating frequency is 300Hz; and 5, taking the hub workpiece out, drying, and polishing the exposed surface of the hub workpiece. The invention provides a process for directly carrying out surface ceramic treatment on a machined magnesium alloy hub.

Description

technical field [0001] The invention relates to a process for treating the surface layer of a magnesium alloy vehicle wheel hub, in particular to a ceramic formula and process for surface treatment of the magnesium alloy vehicle wheel hub. Background technique [0002] Magnesium alloy vehicle wheels have been widely used in the automotive industry due to their small specific gravity and light weight, especially in high-end cars and buses. [0003] Magnesium alloys have low material hardness and poor anti-corrosion and anti-rust properties. The current treatment methods are mostly surface spraying anti-corrosion materials and anodization. The problem of weak bonding between the material and the substrate is prone to fall off, and the hardness of the material is low. The vehicle is scratched by hard objects such as stones during high-speed driving. When the magnesium alloy substrate is exposed, it is very easy to oxidize. [0004] Due to the active chemical properties of magn...
