Abstract

L'invention concerne un procédé de production d'une tôle d'acier revêtue de zinc ou d'un alliage de zinc présentant une résistance à la traction supérieure à 900 mpa, pour la fabrication de soudures par points de résistance contenant en moyenne pas plus de deux fissures de fragilisation par métal liquide par soudure ayant une profondeur de 100 µm ou plus, comprenant les étapes successives de fourniture d'une tôle d'acier laminée à froid, dont la composition nominale contient, en pourcentage en poids : 0,07 % = c = 0,5 %, 0,3 % = mn = 5 %, 0,010 % = al = 1 %, 0,010 % = si = 2,45 %, avec 0,35 % = (si+al) = 2,5 %, 0,001 % = cr = 1,0 %, 0,001 % = mo = 0,5 %, et éventuellement, 0,005 % = nb = 0,1 %, 0,005 % = v = 0,2 %, 0,005 % = ti = 0,1 %, 0,0001 % = b = 0,004 %, 0,001 % = cu = 0,5 %, 0,001 % = ni = 1,0 %, le restant étant constitué de fer et d'impuretés inévitables provenant de la fusion, en teneurs telles que s<0,003 %, p<0,02 %, n<0,008 %, de chauffage de la tôle d'acier laminée à froid jusqu'à une température t1 comprise entre 550°c et ac1+50°c dans une zone du four ayant une atmosphère (a1) contenant de 2 à 15 % d'hydrogène en volume, le reste étant constitué d'azote et d'impuretés inévitables, de sorte que le fer ne soit pas oxydé, puis d'addition à l'atmosphère du four d'au moins un élément choisi parmi la vapeur d'eau ou l'oxygène à un débit d'injection q supérieur à (0,07%/h x a), a étant égal à 1 si ledit élément est la vapeur d'eau ou égal à 0,52 si ledit élément est l'oxygène, à une température t=t1, de manière à obtenir une atmosphère (a2) ayant un point de rosée dp2 compris entre -15°c et la température te du point de rosée d'équilibre fer/oxyde de fer, puis de chauffage de la tôle à partir de la température t1 jusqu'à une température t2 comprise entre 720°c et 1000°c dans une zone du four sous atmosphère (a2) d'azote contenant de 2 à 15 % d'hydrogène et plus de 0,1 % de co en volume, avec une pression partielle d'oxygène supérieure à 10-21 atm., la durée td de chauffage de la tôle à partir de la température t1 jusqu'à la fin de l'immersion à la température t2 étant comprise entre 100 et 500 s., d'immersion de la tôle à t2, puis de refroidissement de la tôle à une vitesse comprise entre 10 et 400 °c/s, puis de revêtement de la tôle avec un revêtement de zinc ou d'alliage de zinc.
