Remanufacturing is a promising technique for reducing manufacturing costs and material usage. This work presents a method for repairing casting parts using an additive metal-layer deposition process. To determine characteristics and mechanical properties of parts repaired using the proposed additive metal-layer-deposition-based method, tensile specimens were designed with grooves measuring 1 mm and 3 mm in depth. Two specific metal powders, AISI-P21 (SCM440) and AISI-H13 (SKD61), were melted using a highly focused laser, and molten droplets were subsequently built up layer-by-layer to fill-in the grooves. Mechanical and metallurgical characteristics of repaired parts were investigated via tensile and hardness tests and microstructural analyses. Experimental results demonstrate that the ultimate strength of specimens repaired using the proposed additive metal-layer deposition method measured approximately 9% lower compared with that of FC300. However, the mechanical strength of additive metal-layer deposition specimen was increased about 22% compared with that of welded specimen. Through this work, we can make a conclusion that the additive metal-layer deposition technique is well-suited for the repair and reproduction of castings.

To reduce the flammability of cotton fabrics, an environmentally benign, simple and effective method was proposed. Coatings composed of phosphoguanidine/ATMP/alginate were deposited on the surface of the cotton fabrics through layer-by-layer (LbL) assembly. FTIR spectra indicate that the layer-by-layer deposition process is successfully carried out on the surface of cotton fabrics. TGA suggested that LbL coating can significantly increase the char residue. The results of MCC and vertical flame tests showed that the LbL coatings can remarkably enhance the fire safety properties of the cotton fabrics and a higher concentration of ATMP (2 wt%) can bring better effect of flame retardancy.

An orthogonally chemically reactive microcapsule is derived from a single polymer following a layer-by-layer-deposition process, where a 1,4 conjugate addition reaction provided a basis for sequential deposition of a chemically reactive nanocomplex.

Tests of devices using a layer-by-layer deposition process for forming multilayer arrays of ferritin have been previously reported that indicate that highly-correlated electron transport is occurring, consistent with models of electron transport in quantum dots. The parametric tests reported in this paper were performed to evaluate this reported evidence in greater detail. As shown herein, the evidence from these studies establishes that layer-by-layer deposition of ferritin does not result in consistent formation of disordered multilayer ferritin structures (DMFS) that are sufficient to create devices that provide repeatable electrical characteristics, but can nonetheless provide additional evidence of highly-correlated electron transport.
