Definitions

  • the invention relates to a first inventive concept a method of creating a wear-resistant surface components made of steel and goes according to another Inventive ideas on a machine with at least one Steel existing component, at least partially with a wear-resistant surface is provided.
  • This task is in connection with the generic Process solved in that the existing steel Base material to form a harder compared to steel Intermediate layer and an even harder outer layer successively several, overlapping layers from one Aluminum bronze are melted, and in connection with the generic machine solved in that for formation a protective covering is provided on the wear-resistant surface, of several, preferably two overlapping, melted onto the base material made of steel Layers made of aluminum bronze.
  • the aluminum bronze preferably melted by welding turns out surprisingly in the outer layer than harder than in the inner layer.
  • interlayer to the steel base material which has a hardness of 100 - 200 HV. This ensures that the Hardness difference between base material and more wear-resistant Outer layer is not overcome in one step, but in several levels.
  • a preheating temperature has to be particularly preferred proven of 350 ° C. This allows optimal hardness values without changing the structure of the base material.
  • Another way to adjust the achievable Degree of hardness to the circumstances of the individual case exists in advantageously in a variation of the composition of the coming aluminum bronze. If one a particularly high hardness can be achieved Aluminum bronze with 13% - 16% Al, 4% - 5% Fe, 0.2% - 0.8% Si, 1% - 2% Mn, at most 0.2% C and the rest Cu are used. A lower hardness can be achieved by using a Aluminum bronze with 8% - 11% Al, 4% - 6% Ni, 3% - 5% Fe, 1% - Reach 2% Mn and rest Cu. In this way, the Hardness of the outer layer and / or the lower layer Adapt the needs of the individual case.
  • a further advantageous measure can consist in that a quickly wearing coating, for example made of MoS 2 , is applied to the outer, wear-resistant layer made of aluminum-bronze in order to achieve good running-in properties.
  • This running-in layer which disappears by itself during the running-in phase, ensures that the hard base layer formed by the outer layer made of aluminum-bronze is only exposed and comes into play after a certain running-in period, which is advantageous for achieving a long time Lifetime affects.
  • the present invention can be used anywhere come where a steel component on the surface a protective covering with a hardness of steel that is 100 - 200 HV is, additional hardness required. This is for example with different, highly stressed treads components of engines, such as piston rings, Crosshead guides or the like, the case. With the help of compared to the base material harder protective covering Reduced wear rate and thus the service life increase. It is therefore as hard as possible stressed surface and the best possible connection aimed at with the basic material.
  • the section of the frame on which FIG. 1 is based of a two-stroke large diesel engine contains two a crosshead 1 flanking stand walls 2.
  • the crosshead 1 has side Sliding shoes 3 which face away from each other at their ends Bearing surfaces having guide plates 4 are provided. These run on mutually facing stands provided on the stand Guide rails with treads 5.
  • the guide plates 4 and guide rails 5 consist of normal steel as the base material and are in the range of their facing treads with a protective covering 6 provided, which has a higher hardness than steel and therefore one long service life proven.
  • a protective covering can of course also with other, similar loads exposed components made of steel, such as bearing bushes, piston rings etc., can be provided.
  • the protective covering 6 is made of aluminum-bronze and is like is best seen in Figure 2, by two on the out Steel existing base material 7 successively overlapping layers melted by welding 8, 9 manufactured.
  • the hardness of steel is usually 100 - 200 HV.
  • the hardness of aluminum bronze is usually in the The order of 200 HV.
  • the one on the steel one Base material 7 first welded on, lower layer 8 has in Surprisingly, a hardness of around 300 - 400 HV.
  • the second, outer layer 9 the result is surprising A much greater hardness of about 500 - 600 HV.
  • the outer layer 9 is therefore particularly suitable as wear-resistant Base layer, which is even in robust operating conditions long life guaranteed.
  • a running-in layer 10 made of a comparatively quickly wearing material, for example MoS 2 can be applied to the outer layer 9, which during the running-in phase disappears of its own accord, so that the outer layer 9, which is made of aluminum-bronze and has a great hardness, then comes into play, as indicated on the right in FIG. 2.
  • the inner layer has 8 in a row their lower hardness, higher toughness and impact resistance, so that surface parallel indicated by the arrows 11, 12 Shear forces and surface normal transverse forces are well absorbed and can be transferred to the base material 7.
  • the thickness of each other welded layers 8, 9 the same. This thickness can be about 1.5 mm be. Different thicknesses or different thicknesses between the layers 8, 9 are of course possible. It would be the same also conceivable to weld more than two layers to each other, although the one on which the example shown is based Version with two welded layers 8, 9 as has proven to be particularly preferred.
  • the 8% - 25% Al at least one of the components Sb, Co, Be, Cr, Sn, Mn, Si, Cd, Zn, Fe, Ni, Pb and C each contain 0.2% -10% and the rest Cu.
  • an aluminum bronze may be desirable Use the 13% - 16% Al, 4% - 5% Fe, 0.2% - 0.8% Si, 1% - 2% Mn, at most 0.2% C and balance Cu.
  • the layers 8, 9 can, as already mentioned above, by a welding process can be applied. You can do one electric arc or laser beams or flames Find use
  • the absorbent Workpiece before the respective application of an aluminum layer i.e. the base material 7 before the application of the lower layer 8 and the intermediate product coated in this way before the application of the second layer 9, are preheated.
  • the preheating takes place expediently in an oven, a preheating temperature of about 350 ° C was found to be particularly useful.
