Repairing a hardfacing coating using AM technologies presents however several simultaneous challenges arising from the complex geometry and a high probability of crack formation due to process-induced stress. We address the repair of a cobalt-based Stellite™ 6 hardfacing coating on an AISI 316L substrate performed using Laser Powder Directed Energy Deposition (LP-DED) and investigate the influence of key process features and parameters. We describe our process which successfully prevents crack formation both during and after the repair, highlighting the design of the preliminary part machining phase, induction heating of an extended part volume during the laser repair phase and the optimal scanning strategy. Local characterization using non-destructive testing, Vickers hardness measurements and microstructural examinations by scanning electron microscopy (SEM) show an excellent metallurgical quality of the repair and its interface with the original part.

The hardness ranged from 206 to 289 Vickers hardness (HV), with a considerable increase at the interface due to concentration of δ ferrite.

The bonding ligament weakens the RFSSW joint because the alclad layer is trapped between the specimens. This layer hinders material mixing during welding and creates a weak interface prone to crack initiation and propagation during external loading, affecting joint integrity. To overcome this problem, a novel tool sequencing variant of RFSSW, the pin plunging reinforced RFSSW (PPRSP-RFSSW), is proposed. A smoothed-particle hydrodynamics (SPH) formulation-based 3D thermo-mechanical model is developed to study the thermo-mechanical and material flow properties as it is possible to trace the field variables explicitly; it can manage significant material/elemental deformations and capture material mixing dynamically. The PPRSP-RFSSW is numerically analyzed and compared to existing sleeve plunging RFSSW (SP-RFSSW). The numerical model's accuracy was tested by comparing temperatures to experimental temperature data in published papers, and the results corresponded well. Comparisons are made between the SP-RFSSW and PPRSP-RFSSW concerning their heat distribution, plasticization, and material flow.

The detachment modes of one drop per multiple pulses (ODMP), one drop per pulse (ODPP), and multiple drops per pulse (MDPP) were analyzed. The experiments were performed by depositing preforms using 308 L stainless steel wire with a diameter of 1.0 mm on a 316 L stainless steel substrate. Characterization of the droplet detachment modes was performed using a high-speed camera and data acquisition system. Geometric analysis of the preforms was performed by photogrammetry. A greater heat input was observed in the ODMP mode. The MDPP and ODPP modes produced thinner preforms with a better surface finish. In addition, the MDPP mode generated better results in the manufactured preforms, with lower hardness and higher tensile strength. However, the ODMP mode led to relatively poorer results, with wider walls, greater surface waviness, and lower tensile strength.

Specifically, a milled groove in an AA7075-T651 substrate was repaired using the twin rod additive friction stir deposition (TR-AFSD) without using any graphite lubricant on the feedstock materials, which is required for conventional square feedstock AFSD. Residual stress distribution in the repaired substrate at different depths was quantified via neutron diffraction, where the distribution of longitudinal residual stress in the TR-AFSD repair was found comparable to materials subjected to other friction-based processes, with an M-shaped or bell-shaped distribution. The tensile longitudinal residual stress, with a peak of 171.3 MPa, spanned the center region around 36 mm, while compressive longitudinal residual stresses, ranging between -112.9 MPa and -12.3 MPa, were balanced outside the center at both the advancing side and retreating sides. The transverse and normal residual stresses were consistent across the repair, with smaller magnitudes between -52 MPa and 68.3 MPa. The non-destructive and high penetration depth nature of the neutron diffraction method enabled the calculation of von Mises stress by interpreting the three measured orthogonal residual stresses as the principal stresses. By normalizing the calculated von Mises stress to the microhardness, this quantified ratio indicates the influence of the embedded residual stresses relative to the material's strength. The higher normalized ratio observed at a deeper depth closer to the bottom of the repair, suggests that the magnitude of residual stresses is closer to the material's strength, indicating a higher potential for residual stress-induced failure at this location. We also calibrated the state-of-the-art smooth particle hydrodynamic (SPH) TR-AFSD process model to predict the von Mises stress distribution in the TR-AFSD AA7075 repair. The experimentally measured residual stress, coupled with the SPH simulation, could further help the research community to minimize the tensile region and alleviate substrate distortion in materials subjected to friction-based processes.</div></div>","PeriodicalId":34313,"journal":{"name":"Journal of Advanced Joining Processes","volume":"11 ","pages":"Article 100283"},"PeriodicalIF":3.8,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143133071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research investigates the effects of assembly speed and ultrasonic vibration power on the reduction of press-fit force. Through a series of 15 distinct experiments employing both conventional press-fitting (CPF) and ultrasonic-assisted press-fitting (UAPF), it was found that increasing the power of ultrasonic vibrations leads to a significant decrease in the maximum press-fit force, whereas reducing the assembly speed has a minor effect. The maximum press-fit force is reduced by over 80 % when utilizing maximum vibration power.

However, the use of CMF in larger structures requires the implementation of joining methods. Solid-state joining processes are particularly well-suited for metal foams as they can form solid bonds between porous workpieces without distorting their cellular structures.
