Enhancement of wear resistance of mulcher teeth with the help of electrochemical coats

Abstract

Influence of alloying additives in electrolyte and conditions of electrolysis on microhardness, adhesive strength and wear resistance of iron and cobalt coats have been investigated. Conditions of creating coats which make it possible to considerably enhance wear resistance of the mulcher teeth under the conditions of abrasive wear have been established. The process of creating wear resistant coats have been approved and recommended to introduction after the service life of the mulcher teeth sets have been extended.

The Effect of the Strength of Components on the Physicomechanical Properties of Composite Materials

“…According to the tests of the obtained ratio carried out on iron-electrocorundum, nickel-electrocorundum, and copper-electrocorundum composites [18][19][20][21][22][23][24], the calculations based on continuum theory (cracks are simulated as elliptical two-sided dislocation clusters) are closest to the real results. Figure 2 shows the volume content corresponding to the highest coating strength by (28) depending on the strength properties of the matrix with the inclusion of electrocorundum.…”

“…The σ p /σ c ratio for this case is (22) It follows from the ratio ( 21) that ( 23) Equation ( 22) allows determining the λ/d ratio for the case considered as (24) Taking into account the dependence of the volume content on the λ/d ratio:…”

“…Electrodeposited alloys and composites have perfect structures (Fig. 3), high elastoplastic properties, wear resistance, adhesion to the base, and lower internal stresses compared with "pure" electrolytic iron [12,18,19,21,24].…”
