Description

(54) METAL-LAYERING GREASING

The invention relates to mechanical engineering, in particular to metal-clad lubricants, and can be used to lubricate the friction units of machines and mechanisms.

Copper-containing lubricants are known that give the effect of selective transfer in steel-steel f1J friction pairs.

The increased wear resistance of pp friction when using these lubricants is explained by selective transfer.

The closest in composition to the present invention is a metal cladding grease containing a soap grease and 5-60% of powders of soft metals, such as copper 2.

However, the known lubricant provides insufficiently high anti-friction properties and wear resistance in a steel-steel pair.

The aim of the invention is to improve the anti-friction properties and wear resistance.

The goal is achieved by the fact that the metal-plating grease, containing the plastic grease and copper, additionally contains an-, LINE and salicylic aldehyde with the following content of components, wt.%:

For the preparation of the lubricant, aniline, salicylic aldehyde, copper powder and the base (CYLTIM20 -201 or CIATIM-203) are mixed in the above proportions at room temperature and mixed thoroughly until a homogeneous mass is obtained. The composition of the formulations of lubricants given in

Composition of metal-clad lubricants Tests were carried out on a standard SMC-2 friction machine according to the scheme. Disc Stal 40-steel 40X HRC-4850) at a relative speed of 1 g

Table of the grooming is 0.2 nominal area of the friction contact l, m, The test results are given in Table. 2. Table 2: As can be seen from the results obtained (Table 2), adding the above additives to various metal-plating lubricants, the total wear of the samples is significantly reduced. When the content in the lubricant composition is 0.05% aniline and 0.30% salicylic aldehyde, wear is practically absent, the value of the friction coefficient decreases. Doping with aniline and salicylic aldehyde has a positive effect on the ability of the lubricant to reduce damage to the rubbing surfaces due to the scoring, characterized by the value of the scoring index (table h). The scoring index values are determined on a four-ball friction machine in accordance with GOST 9490-75. / Table Index scuffing grease composition,
