Micro-fluid ejection heads and methods for extending the life of micro-fluid ejection heads. One such micro-fluid ejection head includes a substrate having a plurality of thermal ejection actuators. Each of the thermal ejection actuators has a resistive layer and a protective layer thereon. A flow feature member is adjacent the substrate and defines a fluid feed channel, a fluid chamber associated with at least one of the actuators and in flow communication with the fluid feed channel, and a nozzle. The nozzle is offset to a side of the chamber opposite the feed channel. A polymeric layer having a degradation temperature of less than about 400~ C. overlaps a portion of the at least one actuator associated with the fluid chamber and positioned less than about five microns from at least an edge of the at least one actuator opposite the fluid feed channel.

Têtes d~éjection de microfluide et procédés permettant de prolonger leur durée de vie. Une tête d~éjection de microfluide de ce type comporte un substrat comprenant une pluralité d~actionneurs d~éjection thermique. Chacun des actionneurs d~éjection thermique est revêtu d~une couche résistive et d~une couche protectrice. Un élément de configuration d~écoulement adjacent au substrat définit un passage d~amenée de fluide, une chambre de fluide associée à l~un au moins des actionneurs et en communication fluidique avec le passage d~amenée de fluide, et une buse. La buse est déportée d~un côté de la chambre opposé au passage d~amenée de fluide. Une couche polymère dont la température de dégradation est inférieure à environ 400°C recouvre une partie dudit au moins un actionneur associé à la chambre de fluide et est appliquée à une distance inférieure à environ cinq microns d~au moins un bord dudit au moins un actionneur opposé au passage d~amenée de fluide.
