| description | This paper examines the topography and roughness of coatings of hard
alloyed materials deposited by electrospark deposition (ESD) on titanium
and nickel alloys with different initial roughness. The influence of the
electrode materials and the energy parameters of the ESD process on the
roughness parameters Ra, Rt, Rq, Rz, Rmax, on the depth of waviness Wt,
the asymmetry Rsk, the excess Rku, on the depth of core roughness Rk and
the depth of the reduced picks roughness Rpk was established. The
conditions for ESD are indicated, under which the traces of the previous
treatment are erased and the characteristics of the initial substrate surface
are improved. The numerical values of the roughness parameters for
electrospark coatings from five types of hard alloys and one type of TiB2
based electrode with nanosized additives have been established. |
