Material description
Babbitt alloy (including tin base bearing alloy and lead base bearing alloy is the most well-known bearing material, with antifriction properties of tin and lead base bearing alloy. Invented by American Babbitt and named for its white color, also known as white alloy, its application can be traced back to the industrial Revolution. Tin base babbitt and lead base babbitt with antifriction properties are the most suitable materials for low axis rotation, compared with other bearing materials, with better adaptability and compression, widely used in large Marine diesel engines, turbines, alternators, and other mining machinery and large rotating machinery. The main alloy components are tin, lead, antimony, copper. Antimony and copper are used to improve the strength and hardness of alloys. The organization characteristic of babbitt is, in the soft phase matrix uniformly distributed on the hard phase particle, soft phase matrix make alloy has the very good embedded hidden sex, compliance and resistance to bite, and after running-in, soft base concave, hard point outward, make form tiny space between the sliding surface, a storage space and channel the lubricating oil, good anti-friction; The convex hard point plays a supporting role and is conducive to bearing. Babbitt alloy in addition to the manufacture of sliding bearings, because of its soft texture, low strength, often its wire or powder sprayed on steel and other substrates into bearing used. Babbitt alloy can be divided into tin base (see tin alloy) and lead base alloy. The latter contains 10% ~ 20% antimony and 5% ~ 15% tin. In order to prevent component segregation and refine grain, a small amount of arsenic is often added. Lead - based alloys have lower strength and hardness than tin - based alloys and poor corrosion resistance. The microstructure characteristics are that hard phase particles are evenly distributed on the soft phase matrix. The soft phase matrix makes babbitt alloy have very good embedding, compliance and anti-bite properties. After running in, the soft matrix is concave and the hard point is convex, forming a tiny gap between the sliding surfaces and becoming an oil storage space and lubricating oil channel, which is conducive to reducing friction. The convex hard point plays a supporting role and is conducive to bearing.

B-2 Hastelloy alloy plateHastelloy B-2 alloy is a ni-MO138-2118-5638 cycle alloy with very low carbon and silicon content. It reduces the precipitation of carbides and other phases in the weld and heat affected zone, thus ensuring good corrosion resistance even in the welded state. As is known to all, Hastelloy B-2 alloy has excellent corrosion resistance in various reducing media, and can withstand the corrosion of hydrochloric acid at any temperature and concentration under atmospheric pressure. It has excellent corrosion resistance in non-aerated medium concentration of non-oxidizing sulfuric acid, various concentrations of phosphoric acid, high temperature acetic acid, formic acid and other organic acids, bromic acid and hydrogen chloride gas. At the same time, it is also resistant to halogen catalyst corrosion. Therefore, Hastelloy B-2 alloy is usually used in a variety of harsh petroleum and chemical processes, such as the distillation of hydrochloric acid, concentration, alkylation of ethylbenzene and low pressure carbonyl synthesis of acetic acid.
The medium temperature thermal stability of Hastelloy B-2 alloy is poor. When the iron content in Hastelloy B-2 alloy drops below 2%, the alloy is sensitive to the transformation of phase 3 (i.e. Ni4Mo phase, an ordered intermetallic compound). When the alloy stays in the temperature range of 650~750℃ for a long time, the phase 3 is generated instantly. The presence of phase 3 reduces the toughness of Hastelloy B-2 alloy, makes it sensitive to stress corrosion, and even causes the cracking of Hastelloy B-2 alloy in raw material production (such as hot rolling process), equipment manufacturing process (such as integral heat treatment after welding of Hastelloy B-2 alloy equipment) and service environment. At present, the standard test method for intergranular corrosion resistance of Hastelloy B-2 alloy is normal pressure boiling hydrochloric acid method and weight loss method. As hastelloy B-2 alloy is resistant to hydrochloric acid corrosion, it is not sensitive to test the intergranular corrosion tendency of hastelloy B-2 alloy by boiling hydrochloric acid at atmospheric pressure. It is found that the corrosion resistance of Hastelloy B-2 alloy depends not only on its chemical composition, but also on the control process of hot working. When the hot working process is not controlled properly, not only the grains of Hastelloy B-2 alloy grow up, but also the high Mo σ phase appears in the intergranular phase. Under this condition, the intergranular corrosion resistance of Hastelloy B-2 alloy decreases obviously. In the HCL test, the grain boundary erosion depth of coarse-grained plate and normal plate differs about twice.- 201 Nickel alloy coilNickel201 is an extremely low carbon commercial pure nickel approved for use in high-temperature environments up to 1230℃.
