On wire drawing lines that run wet<\/strong> \u2014 and especially where acid solutions are involved, as in copper plating tanks \u2014 the mechanical components work in one of the most aggressive environments of the entire production cycle. Chemical corrosion, abrasive wear and the need to keep an impeccable surface finish all add up, pushing traditional materials and coatings to their limit. In these conditions, the material the wire-contact parts are made of is no minor detail: it determines component life, finished-product quality and how often the line stops.<\/p>\n\n\n\n

This is where Kersint\u00ae<\/a> comes in: the sintered technical ceramic based on zirconium oxide<\/a> developed by Paganoni<\/a>, a division of Mario Nava S.p.A. that has specialised since the 1970s<\/a> in anti-wear coatings and technical ceramics for the wire drawing industry. Unlike the other products in the range, Kersint\u00ae is not a coating applied to a surface, but a material<\/strong> from which entire parts or inserts are made.<\/p>\n\n\n\n

Wet drawing and acid baths: an environment that tests every material<\/strong><\/p>\n\n\n\n

Wire drawing reduces the cross-section of a wire by pulling it through a series of dies. When this is done wet<\/strong>, the wire and the line components are immersed in a liquid lubricant; in the case of copper plating tanks<\/strong>, this is an actual acidic electrolytic bath used to deposit a layer of copper onto steel wire. It is a stage that is as delicate as it is common in wire mills.<\/p>\n\n\n\n

In these tanks, the parts in contact with the wire and the solution \u2014 rings, cones, shafts, roughing dies \u2014 face three degradation factors at once: the chemical corrosion<\/strong> of the acidic environment, the abrasive wear<\/strong> of the moving wire, and the need to keep a very low surface roughness (Ra)<\/strong>. Roughness is the parameter that measures surface finish: the lower it is, the less friction the wire experiences as it passes.<\/p>\n\n\n\n

An unprotected metal part in this scenario tends to corrode and lose its finish: Ra rises, friction grows, the wire\u2019s surface quality deteriorates, and maintenance work and downtime multiply. The cost is measured not only in spare parts, but above all in hours of stopped production.<\/p>\n\n\n\n

Kersint\u00ae: a sintered ceramic material, not a coating<\/strong><\/p>\n\n\n\n

The single most important thing to understand about Kersint\u00ae<\/a> is that it is not a surface layer. While the other products in the range are coatings applied onto an existing part, Kersint\u00ae is a super-sintered ceramic material<\/strong> based on zirconium oxide<\/strong> and rare minerals, from which parts or inserts are made in their entirety.<\/p>\n\n\n\n

Sintering is the process that, through heat and pressure, binds the ceramic powders into a compact, homogeneous body. The result is a part that carries the properties of zirconium-oxide ceramic throughout its whole volume, not just on the surface.<\/p>\n\n\n\n

This is exactly what makes the difference in chemically aggressive environments: however high-performing, a coating always has an interface with the underlying metal that can become a point of attack for corrosion. A Kersint\u00ae part, on the other hand, has no layer that can wear through to expose a substrate or detach: its chemical and wear resistance is an intrinsic property of the material.<\/p>\n\n\n\n
