“…In such cases, a deposited material becomes the primary component of the surface layer and, because of high process temperature, melts along with the substrate. Issues concerning the powder plasma transferred arc cladding process were discussed, among others, by Khaskin et al (2016), Brunner-Schwer et al (2018, 2019), Xia et al (2010) and Gao et al (2020) [ 25 , 26 , 27 , 28 , 29 ]. Recently, it has been possible to observe very high interest in the application of plasma and laser cladding processes to make composite surface layers on steels and alloys of non-ferrous metals.…”

The article discusses test results concerning an innovative surface layer obtained using the cladding with powder plasma transferred arc welding (PPTAW) method. The above-named layer, being a metal matrix composite (MCM), is characterised by high abrasive wear resistance, resistance to pressure and impact loads, and the possibility of operation at elevated temperatures. The layer was made using powder in the form of a cobalt alloy-based composite reinforced with monocarbide TiC particles and superhard spherical particles of synthetic metal–diamond composite provided with tungsten coating. The surface layer was deposited on a sheet made of low-alloy structural steel grade AISI 4715. The layer is intended for surfaces of inserts of drilling tools used in the extraction industry. The results showed the lack of the thermal and structural decomposition of the hard layer reinforcing the matrix during the cladding process, its very high resistance to metal-mineral abrasive wear and its resistance to moderate impact loads. The abrasive wear resistance of the deposited layer with particles of TiC and synthetic metal–diamond composite was about than 140 times higher than the abrasive wear resistance of abrasion resistant heat-treated steel having a nominal hardness of 400 HBW. The use of diamond as a metal matrix reinforcement in order to increase the abrasive resistance of the PPTAW overlay layer is a new and innovative area of inquiry. There is no information related to tests concerning metal matrix surface layers reinforced with synthetic metal–diamond composite and obtained using PPTAW method.

Aiming at the problems of the in-situ stress monitoring sensor such as susceptibility to lightning strikes and low accuracy, this paper attempts to design one extrinsic pressure sensor based on the optical fiber sensing technology and F-P interferometer. To this end, it first introduces the structural design of the sensor, which is mainly composed of sensitive diaphragm, single-mode fiber and ceramic ring. The use of silver-plated diaphragms in the air cavity can increase the light reflectivity, thereby improving the monitoring accuracy; the insulating anti-electromagnetic interference material can make the sensor less susceptible to lightning strikes and reduce the risk of damage to the sensor due to lightning strikes. Then, the ANSYS simulation software was used to statically analyze the silverplated diaphragm of the sensor, and obtain the ideal radius and thickness values of the silver-plated diaphragm. Furthermore, to verify the accuracy and lightning protection performance of the extrinsic fiber pressure sensor based on F-P cavity in actual stress measurement, an in-situ stress monitoring experiment platform and a simulated lightning strike experiment platform were built. The pressure and temperature calibration experiments and sensor stress loading simulation showed that the sensor has a cavity length change sensitivity of 1677nm/MPa within 0-10MPa and a stress measurement resolution of 60Pa; compared with the common fiber grating method for in-situ stress measurement, the monitoring accuracy of the designed sensor has improved about 3 times; the lightning strike experiment found by using a lightning surge generator that the designed sensor has a stable operating and anti-lightning performance under the test voltage of 0.5kV. The research findings shed light on the further study of F-P cavity-based extrinsic fiber pressure sensor.

“…Co-based coating by plasma cladding has advantages that cannot be replaced by other processing technologies, such as a high arc stability, a low thermal deformation, an excellent interfacial bonding ability, and lower equipment and operating costs, which have broad application prospects in surface modification [ 4 ]. Plasma cladding technology is an advanced surface modification and repair technology, the principle of which is to use high-energy plasma beams to melt the substrate with its surface metal powder by heat and form a solid metallurgical coating after rapid solidification, thus substantially improving the performance of the substrate [ 5 , 6 , 7 , 8 ]. Due to the process characteristics of rapid heating and cooling of the molten pool part in the plasma cladding process, the rapid cooling of the layer and the difference in thermal expansion coefficients between the substrate and the clad layer can cause accumulated residual stresses, and the larger tensile residual stresses induce fatigue cracks, reducing the wear resistance and peeling resistance of the clad layer [ 9 , 10 ], causing deformation and cracking of the substrate [ 9 ] and affecting the subsequent mechanical processing of the substrate and its serviceability and life [ 11 ].…”

The distribution law of residual stress in multi-channel scanned plasma cladding of Co-based alloy under different process parameters was studied by means of simulation and tests, and the optimum process parameters were optimized. The simulation model of the plasma cladding stress field was established by ABAQUS software, and the influence law of the working current, scanning speed, and scanning mode on the residual stress of the Co-based alloy multi-channel scanning was studied. A set of optimal cladding process parameters were obtained. The residual stress of the cladding layer was measured by the blind hole method and compared with the stress value in the finite element model. The results show that there is residual tensile stress on the surface of the cladding layer. The residual stress along the direction of the scanning path is greater than that along the direction of the scan sequence. The residual stress increases with the increase of the working current. The scanning speed is greater, and the residual stress is smaller. The residual stress of the short-edge scanning is greater than that of the long-edge scanning. The residual stress of the successive scanning is greater than that of the reciprocating scanning. The long-edge reciprocating scanning is the best scanning mode. The best combination of process parameters is the working current of 90 A, the scanning speed of 100 mm/min, and the long-edge reciprocating scanning mode.
