• the present invention relates to a bearing comprising a polymer wherein a ferrous base material is coated with a bronze alloy layer onto which a sputtering layer is deposited which in turn receives a layer of sputtering.
• the polymeric slider is provided, among other elements, with a soft metal alloy, the primary layer and the sputtering layer being joined by means of a bonding layer.
• the layered construction generally comprises sturdy base material such as steel coated with a soft metal alloy and at least one sliding layer which will maintain contact with the lubricating oil film. These layers are generally applied by a coating of a bearing material first adhered to the support and at least one additional layer of a bearing material adhered to the surface of the first bearing material. The outer surface of this latter rolling material forms the actual sliding surface that interacts with the shaft.
• the importance of layers is not restricted solely to the sliding layer.
• the function of the layers is rather found by the interaction between them, each having a specific role in the performance of the bearing, as well as a function with the adjacent layer.
• the bearings are usually provided with more than one layer for longevity.
• the applied layer on the base material aims to provide tack resistance and also to perform with reasonable performance as a sliding layer.
• the primary layer performs poorly both in accommodating minor misalignments between the bearing surfaces and the shaft surface, as well as in the ability to accommodate the particles present in the oil film that would cause scratching or scuffing. surfaces.
• One such solution may be exemplified by depositing aluminum and tin through the sputter process on a primary layer of bronzine material.
• Such bearings have as main feature the advantage of supporting high load capacity.
• the drawback is that the deposited layer has low sensitivity to large variations or discontinuities in the oil film, resulting in potential bearing degradation and compromising long-term performance, impairing engine operation, or even failure. .
• GB 2465852 describes a sliding polymeric layer for improving the performance of a bearing / bearing for use in an engine operating under heavy working conditions.

As a result, this bearing cannot guarantee high carrying capacity, although it has good tack resistance.

• the copper alloy has a thickness between 150 to 400 microns. Note that this primary layer 2 may or may not contain lead.
• Binding layer 3 where present, is comprised of nickel and chromium having a thickness of between 1 and 5 microns.
• Sputtering deposited layer 4 comprises 1% to 40% tin, 1% silicon, 1% copper, 2% iron, the remainder being aluminum.
• the thickness of the deposited layer 4 ranges from 3 to 20 microns.
• the invention relates to depositing this polymeric sliding layer 5 onto a deposited layer 4 by sputtering. More specifically, the polymeric sliding layer 5 comprises a polymeric polyimideimide matrix having a soft metal, a fluoropolymer and a silane based material.
• sliding layer 5 has a concentration of 1 to 14% by volume of soft metal (in the form of powder or flakes), more preferably 11 to 14%, with an ideal concentration of 12.5%.
• Soft metal can be chosen from aluminum, copper, copper, silver, tungsten, and stainless alloys.
• the sliding layer comprises an aluminum powder with particles of less than 5 microns.

• sliding layer 5 has a concentration of 2 to 8% by volume of fluoropolymer.
• fluoropolymer may be chosen from polytetrafluoroethylene and fluorinated ethylene propylene, preferably the sliding layer fluoropolymer 5 is polytetrafluoroethylene (PTFE) whose amount is 5.7%. Note that the use of this fluoropolymer reduces the friction coefficient of the bearing and improves its lubricating properties.
• the polymeric matrix consisting of sliding layer 5 also contains a silane material. These materials promote matrix stability and promote adhesion of the material to the deposited layer 4 by sputtering.
• the silane material may be chosen from gamma-aminopropyltriethoxysilane or bis (gamma-trimethoxysilylpropyl) amine, preferably the silane material is of gamma-aminopropyltriethoxysilane.
• the sliding layer preferably has a concentration of 3 to 6% by volume of a material or mixture of silane materials, preferably being 4.8%.

• the thickness of the sliding layer 5 is from 5 to 20 microns, preferably from 7 to 20 microns.
• the novel concept of the present invention is the combined association of a deposited layer 4 by sputtering with a polymer matrix slip layer 5.
• the intention was to reconcile the best properties of each solution.
• the deposited layer 4 would guarantee good wear resistance and good loadability and, on the other hand, that the polymeric sliding layer 5 offers good clamping resistance. It would thus be expected that at best achieve a combination of the values found in the prior art, that is, achieve a bearing 1 having a loading capacity value of 120 MPa and a value for the tackling load of 85 MPa or greater.
• the constructive configuration of the present invention exceeded the initial expectation, completely justifying the new bearing 1 in terms of cost.
• the cost of a bearing 1 of the present invention is higher than those using only part of its layers.
• bronzine 1 of the present invention would be commercially unviable.
• the excellent tribological results achieved guarantee the longevity of a much higher than normal internal combustion engine, including those of the most modern engines with considerably higher demands.
• the result achieved by bearing 1 of the present invention is so superior to those of the prior art that it is anticipated to be a commercial success for being able to drive an engine beyond current limits and for longer even under poorly lubricated conditions.
• the state of the art notably the Miba patent, clearly states that soft metals should not be used in the polymeric layer as it decomposes, and will transfer these fine metal particulates to the oil and therefore a potential risk of bronzin, ie premature wear.
• the principle of the present invention has a distinct criterion in requiring the presence of a soft metal in the composition of the polymeric sliding layer 5.
• the constructive configuration of the bearing 1 of the present invention works so that the deposited layer 4 is able to absorb part of these harmful impacts. This effect comes from the fact that its chemical composition is also endowed with soft metals. Thus, the deposited layers 4 and sliding 5 work together, providing greater difficulty for bearing 1 to wear out.
• the bearing 1 of the present invention achieved a material index of more than 40% higher than the best values in the prior art, thus evidencing its notable advantage.
• This exam was performed using a heavy diesel engine.
• the applied capacity load was 85 MPa.
• Figure 3 represents a test performed between a bearing of the present invention and another of the prior art.
• the bronzine 1 disclosed in this invention has gone through all the steps without scraping on the bronzine.
• a prior art bearing failed four of the five tests, where three of the failures occurred early in the first stage. Of course this is a considerable difference at the very least.
