“…On the contrary, the friction coefficient for the pair, alloyed layer TiB 2 -alumina ball, is 0.59 ± 0.05 and is considerably higher than the one measured for the couple alloyed layer-tool steel. A similar friction coefficient was found in another work [24].…”

Titanium diboride (TiB 2 ) and titanium carbonitride (Ti(C,N)) coatings are widely used as reinforcing materials in applications demanding high corrosion and wear resistance. In this paper, plain carbon steel has been surface alloyed with TiB 2 by plasma transferred arc (PTA) technique using two different gas atmospheres. The first metal matrix composite (MMC) is produced with TiB 2 particles and argon as shielding and plasma gas. In addition, a mixture of Ar and 5% N 2 was used as shielding and plasma gas for producing of second MMC coating. The microstructure of both alloyed layers consists of primary titanium boride particles surrounded by a eutectic matrix, containing ferrite, eutectic boride, and titanium carbonitrides. The presence of these carbonitrides is more intense in the case of the N-enriched alloyed layer, as it was also proved via X-ray Diffraction. The alloyed layers are susceptible to pitting corrosion in 3.5% NaCl or 1 N H 2 SO 4 . The alloyed layer produced with nitrogen mixture gas is slightly more noble than the one produced with pure Ar. The metallic-ferritic matrix corrodes in 6% FeCl 3 * 6H 2 O leaving TiB 2 particles protruding from the matrix. The wear performance of both TiB 2 MMC depends on the counterbody (tool steel or alumina ball).

“…The revolving electrode was successively in traveling contact with the substrate surface to form the thick deposition layer. After deposition, the specimen was etched by the solution of 10 vol.% KOH + 10 vol.% K 3 [Fe(CN) 6 ] + 80 vol.% H 2 O. The microstructures of the coating were observed by scanning electron microscopy (SEM) (Cambridge-S250KM).…”

“…For example, it has been found to be successfully used in gas turbine engine components, nuclear reactor components, aeroengines or other machine components that would meet rigorous demands to wear, friction, corrosion, thermal cycling [6][7][8][9][10]. But ESD process has not been applied on the spheroidal graphite roll in metallurgy iron and steel industry.…”

Electro-spark deposition (ESD) was adopted for preparing high property coatings by depositing WC-8Co cemented carbide on an spheroidal graphite roll substrate. The microstructure and properties of the coating were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) and ball-disc configuration wear tester. The results show that nanosized particles and amorphous structures prevail in the coating which is metallurgically bonded to the substrate. The microstructures of the transition zone include columnar structure and equiaxed structure. The primary phases of the coating contain W 2 C, W 6 C 2.54 , Fe 3 W 3 C, and Co 3 W 3 C. The results of abrasive test show that the coating has low friction coefficients (μ average = 0.18) and the wear mechanisms are mainly abrasive wear, fatigue wear, and oxidation wear. The maximum microhardness value of the coating is about 17410 N/mm 2 . The study reveals that the electro-spark deposition process has better coating quality and the coating has high wear resistance and hardness.

“…The electro-spark deposition (ESD), also known as electro-spark alloying (ESA), is a surface treatment technique to produce hard, wear and corrosion resistant coatings on various metallic materials [6][7][8][9]. In the ESD process, high current-low voltage electrical pulses of short duration are used to alloy an electrode material (anode) with a metallic substrate (cathode) [10,11].…”
