Microporous chromium plating Chrome plating with enhanced corrosion resistance containing fine holes evenly distributed over the surface (At least 10000 holes per cm 2) Cr mc: Microcracked chromium plating Chrome plating with enhanced corrosion resistance containing fine cracks evenly distributed over the surface (At least 100 cracks per cm 2
The highest rate for Cu, Cr and Ni removals was obtained at pH 9.0. The high efficiency of metal removal, at high pH, might be ascribed to the precipitation of their hydroxides at the cathode. The Fe–Fe and Fe–Al electrode combinations were more effective for the removal of Cu, Cr and Ni from metal plating
After electroplating of Cu, Cr, Ni, and Zn on Corten A588 Grade steel, the metal was cut into 15 × 10 × 3 mm dimension using WEDM (Wire Electrical Discharge Machining, Electronica EcoCut). The crystal structure of the coating is carried out by X-ray diffraction (XRD) using Rigaku, Japan with Cu
Two residual sludges coming from the Cr/Ni/Cu plating industry were dried (110 °C) and fired (1100 °C/1h). Then, both dried (gray colored) and fired (black colored) powders were 5- wt% added to three kinds of glazes (see oxide composition of the ceramic frits in Table 1): (I) a lead bisilicate (PbO.2SiO 2) double fire frit (1000 °C), (II) a double fire frit with low lead content (1000 °C

TERMS IN THIS HANDBOOK Terms used in this publication relate industry practice and are commonly understood by plating professionals. The term decorative plating is used
However, the Cu-Sn or Cu-Ni-Sn IMC spalling phenomena were not detected among the 1, 10, 20, 30, 40, and 60 min reflowed samples. Over 20 min reflowed samples have few remained bumps and the total consumption of Cu and Ni causes to the dewetting of solder. This is quite different from the IMC spalling behavior of Cr/Cr-Cu/Cu

An ionic liquid assisted electroless plating is adopted to prepare continuous and dense Ni-Cu dual coatings on the surface of ZTA particles. The effects of l-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF 4) additive, NiSO 4 and CuSO 4 concentrations on the surface morphologies, coating thickness, and element content of Ni-Cu dual coated ZrO 2-toughened Al 2 O 3 ([ protected
High-entropy alloy coatings of AlxFeCoCrNiCu(x=0.25,0.50,1.00)were prepared on steel bar using the electron beam evaporation plating technology,and the effects of different Al contents on corrosion resistance of the coatings were discussed.The phase,microstructure and chemical composition of the prepared coatings were observed with XRD,AFM and EPMA.The experimental results show that the
The plating thickness of duplex nickel plating will be determined and agreed between the parties concerned. Cr mc: Microgram of microcracked chromium plating surface This is a type of chrome plating containing evenly distributed micro-cracks, which are designed to distribute corrosion current and improve the anti-corrosion

Superhydrophobic nano Cu/Al 2 O 3 Ni-Cr composited coating with a low adhesive force was deposited onto the Q345 carbon steel via electro-brush plating. Surface morphologies of nano Cu/Al 2 O 3 Ni-Cr composited coating were investigated by scanning electron microscope (SEM). Chemical compositions were characterized by energy dispersive spectroscopy

In situ TiCp was fabricated via combustion synthesis in an Al–Ti–C system. The quality of copper plating was easily observable on the surface of spherical in situ TiCp. A study was conducted
Between the (Cu,Ni) 6 Sn 5 IMC layer and the Cu substrate, the Ni(P) plating transformed into Ni 3 P binary and a special Ni-Sn-P(Cu) layer, as shown in Figure 7(b). Park et al .[ 34 ] reported that, in a Sn-Ag/Au/Ni/Cu/Ti solder joint, the primary phase formed during the initial reaction stage is Ni 3 Sn 4 , containing a small amount of
Yoon et al. reported that in Sn–0.7Cu/Ni plating, (Ni, Cu) 3 Sn 4 and (Cu, Ni) 6 Sn 5 IMCs grew at 170 °C for more than 50 days . In this study, a thin (Ni, Cu) 3 Sn 4 IMC formed during reflow seems to grow during a storage test. In Sn–0.7Cu + 2.5Cu balls, a (Ni, Cu) 3 Sn 4 IMC did not form after reflow, as shown in Figs. 4 and

To initiate the plating process, the TOPCon side was contacted with 1% HF solution for 30 s to remove the native and laser-induced oxide, formed at the laser openings. For the following Ni and Cu layer deposition, the laser ablated side of the cell was then immersed in the plating electrolyte while being illuminated by light emitting
