“…Samples of 50 × 50 × 14 mm were cut and polished with abrasive paper down to 1000 grit. Then they were covered with powder of pure TiB 2 (grain size: 10 μm) by mixing the powder with alcohol and applying 0.13 g per cm 2 on the surface of the samples. The covered samples were thereafter heated up to 60…”

“…These titanium carbonitrides detected by X-ray diffraction presumably coincide with the light grey areas in the SEI images of Figures 2(b) and 3(b). As it can be clearly seen from the XRD patterns, only stable phases such as TiB 2 and Ti(C,N) are produced with PTA technique, in contrast to laser alloying techniques, leading also to metastable phases with unknown properties [8][9][10][11].…”

“…As titanium has a strong affinity for boron nitrogen and carbon, it combines with these elements in order to form stable titanium borides, nitrides, and carbonitrides, which can be successfully used as reinforcing materials in metal matrix composites (MMCs). In previous studies, TiN and Ti(C,N) coatings are incorporated on various substrates by cathodic arc ion plating process [1,2], physical vapour deposition [3], and plasmaassisted chemical vapour deposition [4]. In addition, TiB 2 particles reinforce different substrates by electron beam [5,6], laser [7][8][9][10][11], or pulsed electrode surfacing [10][11][12] techniques.…”

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).

SiO 2 -Al 2 O 3 -TiO 2 based composite films about 100 mm thick were deposited on a steel plate by coating the slurry with a brush, followed by drying and calcination. The ceramic coatings obtained under proper conditions were found to exhibit excellent stability over a wide range of temperature. As evaluated by copper electrodeposition method, through-holes were present in the coatings calcined at 700c C or below, while they were eliminated completely after calcination at 1100c C in N 2 . Vickers hardness of the coatings increased with increasing calcination temperature, while adhesive strength went through a sharp maximum at 800c C.

The grains of the materials used in coating slurry were reduced from their initial size of about 10 mm to less than 5 mm in diameter using ball-milling. The ceramic composite films thus prepared were deposited about 100 mm in thickness on a steel plate by slurry coating with a doctor blade, followed by drying and calcination in air. It was found that the coating prepared was stable to heating up to 800c C in air, although the use of overly small grains easily caused cracks on the surface. By optimizing the amount of alkali silicate, however, such cracks could be eliminated from the coating, and the number of through-holes in the coating could be drastically decreased. The ceramic coating obtained by both the control of grain size in powders and the optimal addition of the alkali silicate showed excellent densification, thermal stability and adhesion strength.
