Embodiment 1

[0028] A novel anti-friction and wear-resistant spraying material for sliding bearings, comprising the following steps:

[0029] Step A: stock preparation (by mass percentage): chromium 33%, manganese 22%, boron 15%, carbon 15%, the sum of nickel, molybdenum, silicon is 5%, the sum of phosphorus and sulfur is 4%, tungsten 6%;

[0030] Step B: Grinding: Put chromium, manganese, boron, and carbon into the grinding tank for grinding. After the chromium, manganese, boron, and carbon are bent and mixed, add nickel, molybdenum, silicon, phosphorus, sulfur, and tungsten to grind again, so that Obtain alloy powder with chromium, manganese, boron and carbon as main materials;

[0031] Step C: Granulation: put the alloy powder into the drying equipment for drying, so that the alloy powder becomes agglomerated particles, and the spraying material is a metal particle formed by processing the metal powder;

[0032] Step D: heating: melting the agglomerated particles into a liquid;

Abstract

The invention discloses a novel sliding bearing antifriction and antiwear spraying material, and relates to the related technical field of bearing spraying. The novel sliding bearing antifriction andantiwear spraying material is prepared from the compositions in percentage by mass: 33-43% of chromium, 10-22% of manganese, 15-22% of boron, 8-15% of carbon, 5-7% of nickel, molybdenum and silicon, 1-4% of phosphorus and sulfur, and 6-9% of tungsten. The invention further discloses a preparation method of the novel sliding bearing antifriction and antiwear spraying material. The preparation method comprises the steps of step A, material preparation, step B, grinding, step C, granulation, step D, heating and step E, casting. According to the novel sliding bearing antifriction and antiwear spraying material and the preparation method thereof, the strength of metal can be improved through the mixed use of chromium, manganese, boron, carbon, nickel, molybdenum, silicon, phosphorus, sulfur andtungsten, so that the wear resistance of the metal is improved, a sliding bearing is prevented from being worn through, and the service life of the sliding bearing can be prolonged; and the sliding bearing can be wrapped with an alloy solution so that the sliding bearing can be prevented from being worn through due to excessive use time.

Description

technical field [0001] The invention relates to the technical field of bearing spraying, in particular to a novel friction-reducing and wear-resistant spraying material for sliding bearings and a preparation method thereof. Background technique [0002] With steel as the substrate, porous tin bronze powder is sintered on it, and then polytetrafluoroethylene composite material is covered on it, pressed and sintered. This product has been widely used in self-lubricating bearings. Due to the poor wear resistance of PTFE, this product has limited load-carrying capacity, and the thin PTFE layer and the middle layer on the surface are easy to wear out under high load, which seriously affects the service life of the material. [0003] Therefore, it is necessary to propose a new anti-friction and wear-resistant spraying material for sliding bearings and its preparation method to solve the above problems. Contents of the invention [0004] (1) Solved technical problems [0005] ...
