Dilution Explained | Why It Defines Hardfacing Quality

Dilution is one of the most important — and most misunderstood — parameters in any hardfacing process. In this video, I explain what dilution really means and why controlling it is critical for achieving reliable, high-performance hardfacing results. While dilution is often mentioned in specifications and discussions, its impact on coating quality, properties, and lifetime is frequently underestimated. I discuss dilution in the context of different hardfacing technologies, including: – Laser Cladding – PTA (Plasma Transferred Arc) – other arc- and laser-based hardfacing processes The video focuses on practical understanding rather than theory, explaining how dilution influences chemical composition, microstructure, and performance — and why keeping dilution at the minimum acceptable level is essential for industrial applications. This video is part of a series covering Laser Cladding, Hardfacing, and Surface Engineering technologies, based on real industrial experience. 🔔 Subscribe for more videos on: Laser Cladding • Hardfacing • Surface Engineering • Advanced Manufacturing • Industrial Innovation
