    • 专利摘要:
    A powder mixture for thermal spraying is disclosed which comprises at least two powders of alloys with a different hardness in the range from 200 to 650 Hv and/or a different static coefficient of friction in the range from 0.01 to 0.3 mu s. The protective layers obtained by thermal spraying of the mixture have a heterogeneous, lamellar structure with low internal tensions even at substantial thickness, they have high resistance to frictional wear and very good frictional properties.

    The invention relates to the application of wear resistant coatings, c. Particularly for spraying compositions.
    The purpose of the invention is to increase the wear resistance of coatings.
    The proposed spray formulation is a mixture of powders of two alloys selected from nickel-based alloys containing, in wt%:

    If the ratio of alloys in mixture 15 remains from 90:10 to 10:90. ; The proposed composition can be applied | | to the product in various ways. Isothermal performance: gas arc or plasma. The resulting coatings do not require additional reflow; they practically have no internal stresses; which makes it possible to apply coatings with a thickness of up to 10 mm and is also resistant to temperature loads.
    Example 1. On a reel for drying paper after grinding and applying a nickel-aluminum sublayer (95% Ni + 5% A1), the gas was sprayed with a flame of 3 mm. Oxygen consumption 1000 l / h, acetylene | 850 l / h, spraying distance 200 mm. For each pass, a layer 0.2 mm thick was sprayed while rotating the product at 35, at a speed of 30 m / min. The mixture for sputtering: either consists of two aliases A and B in: ratio 60:40, which have a formula; tav, wt.%:
    : Alloy A (HV 450) Alloy C (HV 400) 40 Chromium 20.0 Chromium 16.0 Molybdenum 5.0 Carbon 0.2 Tungsten 0.5 Nickel 2.0 Carbon 1.5 Iron Rest Nickel Rest 45
    As a result, the service life of the product increases to 3-4 years.
    Example2. The guide is 160 mm in diameter after sand. blasting by gas flame, 0 sputtering in Example 1, a coating 3 mm thick was applied from powders of alloys A and B in a ratio of 70:30.
    The alloys have a composition, wt.%: Alloy B (HV 350) Alloy C (HV 280) Tungsten 5.0 Nickel 4.0 Chromium 28.0 Chromium. 11.0 Molybdenum 2.0 Silicon 0.5 Carbon 1.0 Iron Else

    The service life of the roller increases by 10 times.
    The compositions of the proposed alloys, which are used for sputtering, are presented in the table.
    The coatings are applied by flame spraying in the following modes: gas feed rate, l / h: acetylene 1000; oxygen 1200; gas pressure, bar: acetylene 0,6; oxygen 4.0; powder feed rate 5 kgh; sputtering distance 180-200 mm. I The study of wear-resistant coatings for frictional wear showed that the wear of the obtained coatings did not exceed 0.7-1.0 g / k per month, which is significantly less than the wear of coatings obtained from a known composition.
