Description
Technical field
Field is manufactured the present invention relates to alloy, and in particular to the formula and its production work of a kind of high-performance abrasion-proof alloy components
Skill.
Background technology
Alloy components 650~1100 DEG C have higher elevated temperature strength, high temperature anti-fatigue performance, anti-thermal shock impact property and
Good anti-oxidant, decay resistance, the performance such as abrasion between high abrasive wear resistance and good anti-metal.It is widely used in resistance to
It is close in the manufacture of each type component under the conditions of the industrial and minerals such as mill, corrosion-resistant, high temperature resistant, shock resistance, such as supercritical turbine
Directing vane in seal ring, pilot sleeve and piston ring etc., aero-jet engine, industry gas turbine, Vessel personnel
Piece and nozzle guide vane and diesel nozzeles etc..Alloy is divided into cast superalloy, wrought superalloy and powder by preparation technology
Last metallurgy high temperature alloy.Antiwear heat resisting Al-Cu corrosion-resistant high temperature alloy is to rely on to add the elements such as substantial amounts of Cr, Mo or W and C in pure cobalt
The carbide of formation is strengthened, therefore alloy is easily difficult by processing hardening effect using deformation shaping, can only be using casting
The method made carries out preparation shaping.Antiwear heat resisting corrosion resistant alloy product category is more, wherein greatly with tubing or ring class
Based on, such as alloy seal ring, guide sleeve and piston ring.The current portioned product also main method with static sand casting
Produced, this method is only capable of using once due to a sand mold, therefore have that mass production is less efficient, cost is high etc. and asked
Topic, further, since the casting alloy density that sand casting exists in itself is not high, coarse grains the problems such as, need to such as improve performance need
Later stage isostatic pressed processing is carried out, which in turns increases manufacturing cost, the density of fine aluminium is small (ρ=2.7g/cm), about iron
1/3, fusing point is low (660 DEG C), and aluminium is face-centred cubic structure, therefore with very high plasticity, it is easy to process, can be made into various section bars,
Sheet material.The corrosion resistance of aluminium is good；But the intensity of fine aluminium is very low, structural material should not be made.By long-term production practices and
Scientific experiment, people are gradually to add alloying element and carry out reinforced aluminum with methods such as heat treatments, and this has just obtained a series of
Aluminium alloy.Can also have higher intensity, σ while the aluminium alloy of certain element formation is added the advantages of fine aluminium light weight is kept
B values are respectively up to 24~60kgf/mm2.So aluminium alloy " specific strength " (the ratio σ b/ ρ of intensity and proportion) is surpassed a lot
Steel alloy, as preferable structural material, aluminium alloy has excellent electric conductivity, thermal conductivity and corrosion stability because of it, industrially
It is widely used, as most widely used class non-ferrous metal structural material in industry, is widely used in machine-building, transporter
In terms of tool, dynamic power machine and aircraft industry.Using aluminium alloy replace steel plate materialses welding, construction weight can mitigate 50% with
On.
In recent years, from the angle for considering earth environment etc., the light-weighted social requirement of car body is all the more
It is surging, among car body, for panel (outside plate, inner panel of hood, car door, roof etc.), bumper reinforcement (bumper
R/F), reinforcing material of door anti-collision joist etc. etc., the ferrous materials of steel plate etc. are partially replaced using aluminum alloy materials.It is modern
Under the application backgrounds such as track traffic, bridge, large span, high load, extra-high type building window and curtain wall need it is a kind of have compared with
The material of high intensity and good elongation percentage, 6061 aluminium alloy processing characteristicies and elongation percentage etc. can not meet this requirement.It is beautiful
ALcoa companies of state once prepared 6013 aluminium alloys, and the aluminium alloy has higher intensity and good corrosion resistance.But due to 6013
Aluminium alloy elongation percentage is low, processing characteristics is not good enough, so its application is constantly subjected to limitation.
