substratach
Substratach is a proposed concept in materials science and geophysics describing an interfacial state between a substrate and an overlying layer characterized by enhanced bonding and coherent mechanical coupling achieved through coordinated chemical reactions, diffusion, and microstructural organization. The term blends substratum and attach, and is used mainly in speculative discussions about interfacial design in laminated materials.
Origin and usage: The term substratach first appeared in a handful of conference papers and theoretical reviews
Mechanisms: Proposed processes include formation of chemical bonds across the interface, diffusion of substrate species into
Applications: If validated, substratach would inform design strategies for protective coatings, metal-ceramic and polymer-ceramic laminates, and
Limitations: The concept is debated, with limited experimental replication and reliance on indirect measurements. As such,
