Abstract
The invention relates to the technical field of computer accessories, and discloses a manufacturing process of a corrosion-resistant rotating shaft for a computer, which comprises the following steps: (1) Proportioning, namely preparing the percentages of the components in the corrosion-resistant rotating shaft system for the computer: 0.03-0.09% of carbon, 2-4% of aluminum, 0.1-0.4% of silicon, 1.2-1.6% of manganese, 0.02-0.03% of phosphorus, 0.8-1.2% of chromium, 0.01-0.03% of nitrogen, 0.05-0.07% of nickel, 1.5-2.5% of zinc, 1.2-1.8% of titanium, 0.2-0.4% of tin, 0.1-0.3% of niobium and the balance of iron. According to the manufacturing process of the corrosion-resistant rotating shaft for the computer, through solid solution strengthening of nickel and chromium and precipitation strengthening of microalloying elements niobium and titanium carbide, original austenite grains can be kept refined to ensure that the structure of a quenched and tempered building steel plate is sufficiently refined, so that excellent toughness is obtained, the addition of phosphorus can improve the atmospheric corrosion resistance of the rotating shaft, and silicon can be matched with the alloy to further improve the atmospheric corrosion resistance of steel, and the reason is probably that: the steel is not peeled off at high temperature, so that the steel has strong oxidation resistance, corrosion resistance and heat resistance, and is suitable for computers.
Description
Technical Field
The invention relates to the technical field of computer accessories, in particular to a manufacturing process of a corrosion-resistant rotating shaft for a computer.
Background
The computer is commonly called as a computer, is a modern electronic computing machine for high-speed computation, can perform numerical computation, can perform logic computation, and has a memory function. The intelligent electronic device is modern intelligent electronic equipment which can automatically and rapidly process mass data according to program operation.
A computer, which is composed of a hardware system and a software system, without any software installed, is called a bare metal. The method can be divided into five types of super computers, industrial control computers, network computers, personal computers and embedded computers, and more advanced computers include biological computers, photon computers, quantum computers and the like.
