To enhance the tribological properties of coatings and to inhibit cracking, sandwich-structured composite were fabricated, consisting a Ni60CuMo/IN718 transition layer Ni60CuMo/Ni-coated Cu wear-resistant with four different Ni-coated contents. The results indicate that inhibits crack formation in coating, refined grain structure stabilizes its average hardness at approximately 485 HV0.5. Increasing content exacerbates segregation Cu-rich solid solution phases refines situ-generated Cr7C3,...
The effects of the second phase on tensile properties a high‐Mn high‐Al austenitic lightweight steel processed by thin‐strip casting and subsequently aged at 600 °C for different times are studied. Depending aging time, includes short‐range ordered (SRO) phase, nanosized κ and/or microsized phase. At time 1 min, 2 nm SRO precipitates evolves into 6 intragranular when is 60 intergranular phases exist austenite grain boundaries 480 min. precipitation increases yield strength from 470 to 610...
For improving the wear resistance of low-pressure turbine cowling ring's Ti6Al4V (TC4) alloy surface and suppressing generation cracks during laser cladding, we fabricated TiC/Ti3Al-reinforced Ti-based composite coatings on TC4 through cladding TC4-coated TiC mixed powder with different Ti2AlC contents (0, 10 wt%). Results show that have no due to coated by TC4, hard phase presents a uniform distribution in all regions coatings, physical phases two mainly consist α-Ti matrix phase, TiC,...
