Surfacing – Technologies and Layer Properties (A Review)

“…The components added in the flux which leads to increasing of the hardening phases [2] results in similar effects on hardness and wear resistance. The core wire are widely used in another electric arc processes -TIG [11], [12] and [13] and MIG/MAG [3], [10], [15], [16], [17] 20]. The solid wires are applicable in the MIG / MAG process [4], [8], [9], [10], [18] too.…”

“…divided into the following main groups. The microstructure is examined by optical (OM) [1], [9], [17], [21], [23], [27], [30], [31], [36] ], [42], [43] and electron microscopy (SEM) [1], [10], [11], [14], [21], [22], [23] , [33], [39], [46], [47]. The phase composition is determined by the X-ray diffractometer [18], [23], [27], [31], [33], [36], [39], [45], the transmission diffraction electron microscopy [18] and energy-dispersive X-ray spectroscopy [14], [22], [30], [33], [39].…”

“…In the publications reviewed, the materials used as substrates can be divided into the following main groups: carbon steels [3], [6], [7], [12], [13], [15], [16] 17, 18, 21, 25, 26, 29, 36 and 37; alloyed steels [1], [4], [8], [9], [20], [22], [24], [30], [41] and [42]; highly alloyed steels [5] and [32]; aluminium and aluminium alloys [11], [28], [39], [43], [44] and [45]; titanium and titanium alloys [23], [31], [34] and [35]; ductile cast iron [33] and [40]. The SAS, MIG / MAG, TIG, PST, EBS and LS methods were used to apply the layers to carbon steels.…”

“…In addition, the influence of flux (based on cryolite and three salts -sodium chloride, potassium chloride and magnesium chloride) deposited on the nickel coating was investigated. The results are compared with those obtained by the TIG method [11], where micro and nano SiC particles were also used. It has been found that wear resistance is highest when using nanoparticles coated with flux.…”

Aluminium Metal Matrix Composite Sintering With Electroless Metallized Components

“…Sometimes the сarbon nanotubes perform the function of the unreinforcing phase. To improve the wetting of the non-metallic components of the composite materials (especially in the presence of a liquid phase) and to create better adhesion bonds with the aluminium matrix, electroless metallization of the reinforcing phase is often applied [9][10][11][12].…”
